Why does "next episode" go to the credits when rewatching a show?

My kids are the millionth rewatch of Spidey and his Amazing Friends. Clicking "next episode" skips all the foreign language credits the first time, but every time after that, it only plays the credits. Then, when we choose "continue watching" it only plays the credits, goes to the next episode, and plays those credits. It skips the show entirely.

I hope this makes sense. It's annoying.
