Series Won't Record

I am having issues with my series not actually recording. When I went in and selected record on a program, I selected record the series and it shows up in my manage series. When I go to the date/time of the next episode in that series, it shows a check mark as if it's going to record but it never actually records. However, when I just select record for an individual program, it does record. Does anyone know why my series won't record but an individual selection will?
