Fibaro Motion Sensor driver temp offset not working

I can't seem to get the temp offset to register on the Fibaro 'eyeball' motion sensor. Can anyone else confirm?

I havent been able to get the lux to change. No matter if I open the door, turn the light on etc etc. Its been on 47 lux for the last 2 days.
It does say on the device page *pendingchanges:0 but before it said 1 or 2.
Maybe @mike.maxwell can chime in.
