Odd 3 hour recording?

I happened to notice my Roamio was recording something this afternoon. I thought perhaps it might be just a suggestion, but then I noticed it was a 3 hour recording, one that crossed multiple programming blocks (one hour program, two half-hour programs, then another hour program)



I confirmed that there were no manual recordings set, nor any scheduled recordings set to record long.



I don't have a ready explanation for this. Has anyone ever seen anything like this?
