Also in the same section could you have the option to have no season folder added.

hm....how about leaving season folder name settings <empty>? 

episodes have wrong names but the folders have the correct name.

...just guessing....
You can get different episode "names" based on used scraper and given season/episode number. They might use different indexing, maybe based on DVD order or something.

Have a look:
7 Episodes in season 1: https://www.imdb.com/title/tt0235918/epi...t_eps_sn_1
13 Episodes in season 1: https://www.thetvdb.com/series/the-fairl...official/1

So the file "episode_s01e05" would be "A Wish Too Far" on tvdb and "Chin Up!/Dog's Day Afternoon" on imdb

You have the right folder names as <tv show> will probably be the same.

But not always:
tvdb: American Dad! and American Dad for some languages
https://www.thetvdb.com/series/american-dad

imdb: American Dad
https://www.imdb.com/title/tt0397306/?ref_=fn_al_tt_1
And season1 is always season 1, so you get

Code:

<tv show>\season 1\<wrong name_s01e05.ext>
