How do I remove programs that I have recored, watched, and deleted from my harddrive?

As you can see from this screenshot, the programs I recorder on 2/7 will not remove from the DVR schedule listing, even though I have watched them and deleted the files from my storage drive.
How can I remove them from the DVR schedule?

They automatically fall off weather you watch them or not. I believe this list is only 30 days.

There is no manual way to do this to clean it up? It doesnt do it automatically after you delete the media file - and then you scan library and empty the trash bin. I would have thought this would be normal behaviour?

Think of it as a recording “log”. The recording did take place, no matter if you subsequently erased the file.
