Naming should be like this:
TV Shows
.. / Paw Patrol
.. .. / Season 01
.. .. .. / Paw Patrol - s01e01.ext← episode file;extbeing the file extension
.. .. .. / Paw Patrol - s01e02 - Pups Save A Train.ext← episode file w/ optional episode title
.. .. .. / ...
If you already had the show in Plex, you might need to perform the „Plex dance“ in order to ensure Plex won’t ignore your updated file names as it recognizes the file had already been added.
Plex uses number of properties to identify files… not just the file name. This is supposed to avoid losing e.g. your additions / user ratings / view states when you do minor fixes to a video file. Here this can however „protect“ the wrongly matched show’s from being fixed.
For that to work…
- move the show outside of the tv show’s folder
- re-scan the library and wait for the process to complete
- empty trash for this library
- move the files / folders back in place (ideally after completing the naming clean-up)
- re-scan the library
