The only thing I can suggest ATM is to follow the instructions as if your life depended on it, when structuring TV Shows (under ANY agent, or none):
https://support.plex.tv/articles/naming-and-organizing-your-tv-show-files/
Date-Based Television Shows
TV Shows that are date-based should be named as follows:
- /TV Shows/ShowName/Season 02/ShowName – 2011-11-15 – Optional_Info.ext
- /TV Shows/ShowName/Season 02/ShowName – 15-11-2011 – Optional_Info.ext
Where you specify the appropriate date. The date can use either the YYYY-MM-DD or DD-MM-YYYY formats and can use different separators:
- Dashes (2011-11-15)
- Periods (2011.11.15)
- Spaces (2011 11 15)
I do mean dot every i and cross every t.
and do not rely on Refresh Metadata to show immediate changes to an item Plex has in it’s Maw already.
Name and structure this thing appropriately - outside of Plex - right in the middle of a Plex Dance:
Then as soon as it gets there - Unmatch it (using the new agent, of course). For The old Agents - Fix Match/Search Options/Change Agent to Personal Media.
Apart from that advice - we’ll have to wait for more official support. Some of this stuff for the new agent may not work yet, for all I know.
