Too many reservations - recording failure

[Ebor]

I've got the too many reservations error when trying to add a recording.

I've re-tuned and turned on and off several time but this hasn’t worked, I’ve also done a factory reset but again fault appears.

There are currently no scheduled recordings but I can't add a single one due to this error. 

The usb has 45Gb to spare..

The TV is a UE49MU7070 with smart hub which has worked perfectly until now

Please advise as we found this so easy to use.

I fitted a smart plug socket (Tapo TP-Link) a few weeks ago. It is set to turn off the power to the TV in the early hours of Monday and Friday mornings for 1.5 hours. I have had none of these problems since.
