Skytech Fireplace won't turn off

I have a skytech Fireplace controller that detects as a rfp5 remote. It turns on the fireplace just fine but won’t turn it off. I can only record the turn on command and the turn off just won’t record but does control the fireplace just fine. Is there a compatibility issue with these?

Were you able to get this solved? I had a similar result with a Superior EF-BRCK Fireplace Remote.
