So I just spent almost an hour on the phone AFTER two chat's and I ended up figuring this out on my own.
I had marked everything as unwatched already and also watched them all the way through and they did not appear in my recently watched but still did appear in the annoying continue watching queue.
What I did was I went to the continue watching queue and clicked on the episode and marked it "watched" and then immediately marked it "unwatched" and clicked exit for each program and that took care of it.
It's a ridiculous feature because there is already recently watched and it seems to pick up shows that you actually watched start to finish so why continue? Classic Xfinity!
