Specials and extras in TV?

[v6u2w]

Took a look at an older show I remember I had trouble with, this is how it reacts:

It has 4 seasons, one special "Final Episode" without a season. One folder with extras.

With the following folder structure:

Code:

S01
S02
S03
S04
S05
S06 - Extras

S05 folder has the "Final Episode" in it. 
I get this structure in Jellyfin:

Code:

Season 1
Season 2
Season 3
Season 4
Final Episode
Extras

S02-04 are normal.
Final Episode have the final episode.
Extras have the extras.
S01 have S01 episodes, the final episode, and the extras. 


When I change folder structure too:

Code:

S01
S02
S03
S04
S05
Extras

I get Jellyfin structure:

Code:

Season 1
Season 2
Season 3
Season 4
Final Episode
Extras

S02-04 are normal.
Final Episode have the final episode.
Extras have the extras.
S01 have S01 episodes, the final episode. Not the extras any more. 


When I change folder structure too:

Code:

S01
S02
S03
S04
Final episode
Extras

I get this in Jellyfin:

Code:

Season 1
Season 2
Season 3
Season 4
Extras

S02-04 normal.
Extras have the extras.
NO Final episode directory.
S01 have the S01 episodes, and the final episode. 


How the heck do I get rid of the final episode from Season 1? It's weird.
