I came here looking for answers because I have the same problem.
My CPU has been re-running the commercial detection on shows for the past few months over and over.
It doesn’t do it for every show, but I think it’s doing it for shows that it wasn’t able to detect commercials on the first time. So then it tries again the next night (which will likely fail again since nothing has changed).
There was one user that mentioned this could be a possibility a while ago:
If this is the case, that’s a bit disappointing.
