I set up the Mom TV series & Plex is not recognizing the seasons, it has grouped all the shows together, I have 188 tv series that do show the seasons.
I have tried to change the folder names, gave it its own directory, removed it & reinstalled it and rebooted Plex, nothing is working!
If you haven’t already, try manually forcing the series to display seasons. The default setting is “Library Default,” which is supposed to inherit the setting from the library. To change this, edit the show (pencil icon in the bottom-left of the show’s poster when hovering your mouse over it) and navigate to the Advanced section. Change the Seasons setting to “Show” from its default of “Library Default.”
Good then you have some renaming to do.
Please look up the ordering of the episodes on TheTVDB.com
It may be that the DVD release is using a differing episode order.
If you plan on adding more tv shows, I recommend you to invest into Filebot
It makes renaming for Plex a snap.
