DVR Won't Record Daytime Jeopardy

In the four years we've had Cox, I've recorded "Daytime Jeopardy" every weeknight. This series is a repeat from a year ago but it's new to me because I don't watch it "new". On Friday July 27, they said a tournament would start on Monday. Instead we got a repeat of the regular show, from earlier in the season. I would watch it anyway but my DVR won't record it. I go through the routine, it says it's set to record, but it doesn't. The box is only 36% full. Maybe something to do with it being a repeat of a repeat?
