Incorrect Total Episode Count for Specific TV Show

“Professor T” is listed on my Progress Screen and showing a total available episode count of 30. The problem is that the total count of 30 includes the episodes in season 4 and season 5. None of those episodes yet has an air date. So, I don’t think it should appear on the Progress Screen, and the total episode count should probably be 18. The only unusual thing about this show is that I have marked one of the episodes without an air date as watched. That is because I did find it somewhere and watch it. It is fairly common for some episodes to really be available somewhere and not yet have a TMDB air date because they haven’t yet aired on what TMDB considers to be the originating source for the show. I suspect that my marking that episode as watched has triggered the issue. And perhaps it would make sense to have the total episode count include that episode and thus be 19. But that should not trigger its appearance on the Progress screen.

The following screen shots illustrate the issue:
