Problem detecting anime Kono Subarashii Sekai ni Shukufuku o! 3 Bonus Stage

I tried everything, i have 191 animes correctly mapped in my plex, but that OVA for anime Konosuba dont detect at all, it even not show in my library, if i try to find the episode using folder view in plex, it shows de folder but dont show any episode inside, the only way to add the episodes in plex is to fake out as another anime, please help me to fix that.
