Zooz 4-in-1 temp scale can't be changed

No matter where I set it in HabMIN to Fahrenheit it always stays Celsius in PaperUI. If I try and change it in Paper UI I get ERROR: 500 - Internal Server Error.

I’m using openhabian 1.3 so I can’t find the G-D config file and I think I just going to wipe it and be done with this mistake and just buy a controller that actually works. Way too frustrating. Every little thing is a battle to make work if it ever works. And if it does work it’s generally half-assed.
