I have a hunch that the hyphen and the number in the show’s title don’t help.
- Rename your season folders to use 2-digit numbers
Season 01 - Insert a hyphen, separated by spaces before the Season/Episode code
Stargate SG-1 - S##E## - put the whole show aside, make sure you got the Plex Dance correct. All steps in exactly the noted order!
- Perform the Database repair procedure:
