i can't mark a show as watched.
all season and episodes are marked as watched so

If you have watched a tv show, do you not watched all episodes??

EDIT:

I seen the same
Importing library to Ember and just one show get the view mark but all seasons an episodes are marked as viewed
If I try to mark it as unseen all marks is gone as expected, but if I try to set it as seen again it's back to not mark the show itself

Oh, now i understand the problem Yes, it's a bug in tvshow view with calculating. Will be fixed in next alpha.

EDIT: I hope it will be fixed in next alpha

thanks again for the answer.
i explained bad

Also fixed for Alpha 12: Commit
