Again... I can't set up a recording through Xfinity.com

I go to Xfinity.com, find a show I want to record, set it up to record, and it won't show that it will record, and it won't let me cancel.  It says the recording already exists... but, I know it doesn't, because every time this happens, I get home to find the recording not on my DVR.

I am SO sick of Comcast.  I absolutely HATE you.
