DVR won’t cancel recordings, recording episodes in duplicate , triplicate, etc

This is the same issue that a bunch of us experienced last year. I can’t add onto that post because it’s closed, but this is the same issue. No matter how many times I cancel some shows The DVR is automatically UNcanceling them shortly after. And similar to last year it is recording multiple copies of the same episodes over and over and I can’t cancel them to prevent . This was a very annoying issue last year, and there were many unproductive responses from xfinity essentially blaming the users until it finally just “went away”. Hopefully we can cut through all the usual back and forth—as most users on this forum are  adept at using the dvr and can recognize when functionality has changed versus their own behaviors—and just get the issue addressed with whatever solution fixed it last year. I have made no changes to the way I record. I have made no changes to the way I use and watch my DVR at all. The cancel functionality was working fine for months, and now it doesn’t. And suddenly the DVR is not smart enough to not record the same episode 10 times in a matter of days. Thanks!
