I’ve been having this trouble for the past 2 weeks or so. ever since 1.22
Majority of my stuff is anime, and openings and endings I have organized as season 00.
The weird thing is it is actually eventually will play what you selected to play, its just at the very end of the queue if you look at the play queue, my fix is to use 1.21 until it is fixed and it seems plex staff is aware of this issue too so we are not crazy.
Also, if you get on an app like the plex android app and try to play that season 00 it will play fine, at least for me it does but on web and windows app it won’t
