Check your naming and organization. Plex is very picky with TV shows.
If mp4 files, embedded metadata may be tripping up Plex’s ability to match. Check Plex Media Server Settings -> Agents -> Shows. Local Media Assets should be checked, but should also be the last agent. Drag it to the bottom of the list if it is not already there.
If you have to rename/reorganize, suggest you Plex Dance both shows. This clears out any bad matching, metadata, etc from Plex’s database.
