Suggestions suddenly completely random?

I've had my Roamio Pro for almost 2 years now, and it had gotten pretty good at knowing my tastes. I actually used the suggestions listing quite a bit; there was always something in there I'd want to watch.

Recently - and I want to say it's since the Rovi listings took over - something has gotten REALLY screwed up. At first I had the issue where it wasn't recording anything; I've seen other people talking about that, but it seems those people had that issue resolved and mine did eventually start recording again too.

But now it's just recording a bunch of garbage. I mean obviously Spanish language programs, talk shows about college basketball and NASCAR, collections of short films, game shows, Fox News channel news magazines, I mean this is literally all stuff I have NEVER watched. It's almost not even random, it's almost the *opposite* of what I watch and have given thumbs up to.

Has anyone else been experiencing this? I wonder if this is one of those "toggle something off and then on" things to fix, but I'm afraid of losing all my thumb ratings or whatever if I reset it. I mean I've been holding out hope that it suddenly fixes itself, but it hasn't yet.
