Series recording won't "stick" Part 2

I have lots of programs set up to record automatically on the Contour DVR. All was well until a couple of weeks ago when one program mysteriously stopped recording (The Tonight Show with Johnny Carson on Antenna TV).  I have deleted the program from the series and added it. When this happens the programs shows up in Scheduled but then disappear soon thereafter. Rebooted a number of times, no change.

Not sure if this is happening to other programs.

Any help appreciated.
