This workaround is still spotty. Seasons 1-3 and 6 of Star Trek TNG work. 4-5 do not. Everything for 4-5 is presented at the Season level despite certain files having episode level naming conventions.
I did the Plex dance for Season 4-5. Refreshed metadata multiple times.
What do you need to troubleshoot?
EDIT: Below are example file names that show at the Season-level. Expected behavior is they should be Episode-level.
..\Star Trek The Next Generation\Season 4\Star Trek The Next Generation - s04e01 - Deleted Scenes-deleted.mkv
..\Star Trek The Next Generation\Season 4\Star Trek The Next Generation - s04e01 - Promo-trailer.mkv
