…etc
Plex is able to auto match, and when I go to fix the match I see that there is an entry for California’s Gold, but for whatever reason it only seems to be able to pull the episode name and description for the first episode of each season. I tried manually adding a .plexmatch with the tvdbid but that didn’t help. Is this a common issue?
Restart Plex Media Server
There is a bug in 1.32.8. Occasionally, the Plex agents will not initialize correctly. When this happens, new media is not correctly added to the system. The workaround is to restart PMS. The bug is fixed in 1.40, current beta/Plex Pass release. Read the 1.40 release notes before updating, as there are database changes as well.
Embedded Metadata
Plex may be trying to read embedded metadata from the mp4 files. If the information is incorrect, Plex will not correctly match the media. Check if Plex is configured to use local metadata and try disabling it.
Note: This is a library setting, and will affect all shows in the library.
I added the show to my server. It matched correctly and pulled metadata. The only thing missing is posters for seasons and episodes. I switched episode ordering from TMDB to TVDB, but it made no difference.
The “Prefer local metadata” option was already unchecked. I just scanned again and the metadata filled in correctly. I also reverted back to my original file naming and it’s still matched correctly.
