Recorded shows not in My Shows list

I have seen this a couple of times now. My Roamio Plus is recording shows as I can see from looking at Live TV. All 6 tuners are tuned in to various channels and one is recording, but that show is not in the My Shows list. The list shows two shows as still recording, but they recorded much earlier today. As I said, I have seen this before, and after restarting the TiVo, the recorded shows will show up in My Shows and all will be fine for some time...until it happens again. I have now opened two support tickets on this subject and I don't really have high expectations for the issues to be fixed...I am frustrated with TiVo's support web site and the lack of real answers. Is anyone else seeing this behavior?
