I have this show that I created custom meta data for (Title, release date, and summary) that has quite a few episodes, and several seasons. I just finished adding another season of it, but to get plex to recognize it, I need to update the library, and from experience that’s always deleted my metadata, so I just have a list of episode 1, episode 2, etc, with no meta data. I really don’t want to have to insert the meta data again, since it took me hours to do.
How are you editing it? are you leaving the orange locks in place?
for Plex see new files whether it matches them or not you need to do a “Scan library files” if that is what you are refering to as an “update”
I have a couple test shows that do not exists that i added metadata to and have not had that data disappear after an update

For each episode I put in a title, date available, and the summary. The locks are in place, yes, but in the past my meta data would reset regardless of if they were in place or not, when I hit “Update Library”. Where is this “Scan Library files” thing, I don’t see the option for it anywhere.
here. are you using the “local” web app via ip:32400/web ? but regardless both if these do the same thing. ( local web app will change hosted is usually the newer version )
if you look a the xml for a file does it show fields are locked?

Excuse my noobness, but what do you mean by that?
go to an episode and click the ellipses on the bottom right when you hover on episode thumbnail to and choose get info. on the file info popup on the bottom left you will see a link that says “view XML”
the xml will look like below. on the bottom you can see the fields which are locked. listed and should correspond to ones with orange lock icon ( note posters should always be locked if you chose on specifically though it will not listed here. I just want to make sure there is no discrepancy between them, if they are locked even refreshing metadata should not alter them. I have title and summary locked in example below

Hi, great info above but I just want to add something. I’ve been without home internet for nearly 2 months now (moved house) and got connected yesterday. Updated to latest version of Plex (no manual update button wtf?) and all my ‘locked’ content got messed up.
For example I have the Minion short films set as a series (for my kids, obviously) with names, images etc are all were locked and stayed set in the past. Now they’re named DC Universe shorts and every episode has been renamed. There are others too but I can change them with little issue. Its just a tad annoying.
Thought I’d add it as the OP may have hit a similar issue.
It’s not working. I have some boxing matches, with their own title and sorting title, that are both suppose to be locked, but when I update the library they both reset still.
Basically, I have a new season of the show I want to add to plex, but if I hit “Update Library” to do so, then I will reset all my shows custom episode titles, and episode summaries, which took me a long time to do.
Cna you check what he GUID is for your show? in the same XML it will look like this
guid="com.plexapp.agents.none://33677/1/1?lang=xn" it may say something like “local:33677” ( which should still be fine) just trying to figure out what may be different about our set ups.

Is this it?
guid=“local://4408”
Locked fields can get removed if PMS thinks the file it is scanning is not the same file that it scanned before. When that happens, PMS creates a brand new entry in it’s database. It isn’t technically not-following the lock, it’s a brand new entry so there are no locks.

This indicates that PMS has not matched the file to any movie. If nothing ever changes with this file, then PMS shouldn’t change either. But if something does change, then the above could happen. To prevent that, use the “Match” option from Plex Web and do a manual search. Change the agent to “Personal Media”. Now, Plex will not try to create a new entry even if something changes.

The show doesn’t exist to do a manual Match search. My only option to get the new season I made is to update the library (that I know of at least), will that change the outcome from what you stated?
you can do a manual match but choose Personal Media Agent rather than thetvdb or themoviedb. which is what is indicated by the NONE in this GUI
guid=“com.plexapp.agents.none://33677/1/1?lang=xn”
( but honestly it should not matter afaik i have a test show in both scenarios and both are fine after library updates.)
are the files for existing seasons you already have being changed in anyway. if you are only adding new files then the old files should be the same i assume. Your show files are in the correct folder structure for a TV show ( at least its own show folder ) and are just adding a new season folder with episodes files?

Yeah, everything is in the correct file structure, and all I’m adding is a new season folder with episode files.
suggest first Optimize the Database then make a back up of your PMS folder https://support.plex.tv/hc/en-us/articles/201539237-Backing-Up-Plex-Media-Server-Data.
then do an update and if it happens again show us the server and scanner logs. it might have info on why it thought your existing files were new files.
you can then restore the PMS folder if you want ( which will not have new file info of course )

Doing a manual match and selecting Personal Media Agent removed my series & season posters and banners, which is no big deal and easily fixed. I then updated the library and it added the next season and didn’t change anything else. Thank you very much!
I was having this problem as I added Episode(s) I would scan whilst other Episode were being converted, each subsequent scan would add new episode(s) correctly, but information for the ones before were lost, this happened whether I had added additional details (Tags, poster, title, sort tittle).
When I scanned with all episodes loaded on file store and not previously scanned no problems
tried this on 4 different single and multi season tv shows
