At least it’s not embedded metadata making your life miserable.
TVDB is handling that with Plex - and doing a fine job. Apparently.
Briefly (which is how long I messed with the ONE show requiring it Firefly), do your names match the DVD order at TVDB?
If so: Plex Dance the entire show for major Do-Over and see what you come up with.
In the end - it’s probably just easier to name your files following the ‘air date’ TVDB has listed. Seems you could have done that long ago and been watching this thing.
I’m not at your house tho, so I don’t know the details.
