Bug with Acquired Episodes

Very thankful you added the acquired filter to the "manage watched" episodes page! I've run into two issues I wanted to flag:

Acquired status stuck on specific show
For the show The Challenge, I have four seasons (17-20) that I previously marked as acquired and have since removed. However, they continue to appear in the Manage Watched Episodes page with the acquired filter on, no matter what I try. I've attempted marking them acquired and removing it again, as well as re-adding the show entirely. Nothing resolves it. This appears to be show-specific: I tested the same thing with Taskmaster (marking seasons not-acquired and removing them) and it worked perfectly.

Removing all acquired watched seasons
When all acquired watched seasons are removed from any show, it also automatically removes all not-acquired episodes. I was able to reproduce this with both The Challenge and Taskmaster.
