I'm naming it that way, because otherwise Jellyfin can't handle it properly for me. Season 2 will not show up with the proper metadata if I put all of it in the same folder. My guess is that because 2014 (season 1)and 2015 (season 2) are two separate entries in both Anilist and AniDB and not grouped together under UBW, that it wants it that way in Jellyfin too.
