DVR510 will not erase recorded programs

[JRF61]

I recently finished watching a few recorded shows on the DVR and then erased them. They would be removed from the list. I returned to normal programming. When I returned to the DVR recorded show list, the erased shows are still there.
I checked and none of my shows are "protected". I have tried to erase the same shows 3-4 times and they will not erase. I have a DVR510. Does anyone else have this problem or can anyone tell me what I can do to erase these programs. Thanks in advance.

I had the same problem with my 508 once. I reboot (and I think erased again) and have not not had the problem since.

Thanks DishSubLA, I rebooted & it is working fine. This is the first time that has happened to me. Thanks for the quick response.
