HABpanel odd issue with slider widgets

Hey guys, I have and odd issue with slider widgets in HABpanel.
Whenever a slider widget’s state is changed to 100 or 0, the state shows as NaN in HABpanel until I refresh it manually. But if I change it to any other value it remains that value. these are all Dimmers in my house
and if i operate them manually their correct states show within HABpanel.

Any Idea’s as to why this would be happening? I’ve recently migrated from openhabian 2.1.0 on a rpi2. to a much more powerful Intel I5 system running ubuntu 16.0.4 server LTS and openhabian manually installed.
I never had this issue before with the raspberry pi setup.
