Not seeing all TV files

similar is not relevant.
It has to be compliant to this:
https://support.plex.tv/articles/200220687-naming-series-season-based-tv-shows/

Please show your used folder and file names.

Do also this before experimenting further:
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

After you have renamed folders and files to be compliant, perform the Plex Dance.
