Without more detail, we will not be able to help you much. It matters a lot which tv show we are talking about, since there can be different lists of episode number, titles and order. What matters to Plex is what is used at thetvdb.com
With tv shows, also the whole folder structure where the files reside in, is very important, so please don’t leave that out.
Is the file a mp4/m4v container?
If so:
Go to
- Settings - Server - Agents - Shows - TheTVDB
In there, grab the line ‘Local Media Assets’ with your mouse and drag it downwards, so it ends up being at the bottom of the stack of active agents.
Repeat the same under
- Settings - Server - Agents - Shows - TheMovieDatabase
- Settings - Server - Agents - Movies - Plex Movie
- Settings - Server - Agents - Movies - TheMovieDatabase
Afterwards, Refresh Metadata of the whole show.
Was the file misrecognized before and you renamed it just now?
