Two Fibaro motion sensors behaving differently

I have two Fibaro ZW5 v3.3 sensors in my home and I noticed that one of them is not working as well as the other.

The Hallway sensor shows:

  • Acceleration
  • Battery
  • Illuminance
  • Motion
  • Tamper
  • Temperature
  • Three Axis

The Kitchen sensor is missing

  • Acceleration
  • Tamper

Also, the Kitchen sensor is reporting illuminance as 0, and two pending changes. It is also showing a few less items in the 'State Variables' list.

How should I go about fixing the illuminance reporting from the kitchen sensor and remove the pending changes?
