Watched episode not showing up as watched while showing up as watched when looking in the season itself

when looking on season level it shows that I haven’t watched 3 out of the 11 episodes but when I click on the season it shows I watched 11 out of 11 episodes. this also results in the show showing up on my tvshows tab. is there any fix already tried unwatching everything and selecting them as watched again. is there any fix or is this a known issue?
