You are correct, and I have already configured Plex to add “T:\ServerFolders\TV Shows\Kings” to the TV Show library. So, unfortunately, I don’t believe that is the problem here.
And just to make sure, “T:\ServerFolders\TV Shows" is not added to any TV show library, correct?
One more thought…
Any chance bad embedded metadata is throwing off matching?
If configured to do so, Plex will look at metadata in MP4/M4V files. If the metadata is incorrect, it may cause Plex to incorrectly match things.
You can use MediaInfo or similar tools to view metadata.
To check Plex settings:
If you are using the Plex TV Series scanner & agent, edit the library, choose Advanced, and check the setting for Prefer local metadata. If selected, Plex will prefer embedded metadata over online databases. If you change the setting, refresh the metadata for the library.
If you are using one of the legacy agents, go to Settings → Agents → Shows. Drag Local Media Assets to the bottom of the list in all three sections (or just deselect it in all three). Then refresh the metadata for the library.
