Pioneer AVR Binding constantly changing values back and forth from UNDEF

I added the pioneer avr using discovery in paper UI. I am having two problems.

  1. it is constantly writing to log that the state changed from UNDEF to something for all channels
  2. How do I set a slider in HABPANEL with minimumm as -80 and high as 12 (sent thru REST for this item state description)? When I enter these values, HABPANEL keeps going back to 0 or 1.
