The issue should be fixed at TMDB, and later today or tomorrow I can delete the episode at Trakt too (I need to wait just to make sure the episode doesn’t come back after a refresh).
Do you happen to have extra permissions on TMDB or a contact? I have updated shows with similar issues, created reports and they just sit there for months with zero movement (I don’t think that superboy mod likes me).
Trakt uses TMDB. Is it correct there? If not, you’ll need to report it there. Once it’s fixed trakt can remove it, otherwise it will come back on refresh.
It’s like you sent a reply without reading my messages. I mentioned above that everything is correct on TMDB and only part 19 should be deleted on TRAKT.
