TV Show: Plex Only Recognizing Half the Episodes.

I renamed just that episode so far and did the Plex Dance, step by step, but to no joy. No change at all.

The Plex Dance®:

  1. remove entire show from library <----Danger, Will Robinson, Danger!
  2. update library
  3. empty trash
  4. clean bundles
    https://support.plex.tv/hc/en-us/articles/200392106-Library-Actions <— update libraries, empty trash, clean bundles
  5. repair file names
  6. replace show into library
  7. update library
    All Steps. In Order. No Shortcuts

FileBot - link in my signature - can pre-match and re-name every single episode in this entire series (while it’s OUTSIDE the library) in 5 seconds. Drag and drop, folders and all, into the left pane, click ‘Match’, then arrow down to ‘Edit Format’, select Episode Format, select ‘Firefly - S01E01 - Serenity’. Now FileBot will remember.

Your entire show is already in the left pane so… click Match again (this time with feeling) and click TVDB as the database. 2 or 3 seconds to negotiate the net get the info and apply it to your files. Rename and BOOM! All done. If you have figured out the {Plex} Profile and have also figured out how to use it FileBot will also rename all your folders for you - otherwise you’ll have to do that yourself.

After having done the First 4 Steps above in The Plex Dance® (we’re now on step 5) you have nice clean bundles and Plex is ready to receive your brand new show. Step 6 and 7 await your attention. There is a reason The Plex Dance® was invented. It was invented as a ‘work-around’ to about a 40 year old bug (slightly exaggerated) in Plex that the developers are unwilling/unable to correct wherein once Plex gets it’s teeth into a bundle (in our case a bogus bundle), it takes The Plex Dance® to get Plex to drop the effing bundle!
