Edit: Noticed you have things working. Was typing my reply & didn’t see your follow-up until later…
Make sure you follow Plex’s guidelines when it comes to TV show naming and organization. Plex is a bit forgiving for movies. Not so much for TV shows.
Here’s the guidelines. The second two links will have the detail for TV shows. The first is the Table of Contents with links to info for movies, home movies, etc.
Naming ‘Series’ & ‘Season’ Based TV Shows
Here’s an example (from the TV Show Specials doc). You can use either Specials or Season 00 for the subfolder.
/TV Shows
/Heroes
/Specials
Heroes - s00e02 - Countdown to Season 3.mkv
/Season 01
Heroes - s01e01 - Genesis.avi
Also, if you rename/reorganize the files, you’ll need to perform the Plex Dance.
The purpose of this is to remove all cached metadata and xml data for an item that Plex usually keeps. This helps when you want to “start from scratch” for particular item
- move all files for the media item out of the directory your Library is looking at so Plex does not “see” it anymore
- update library ( scan for media items )
- empty trash
- clean bundles
- double check naming schema and move files back
- update library
