Can't get ABC (Advanced button Controller) to work as I want

I am using Ikea 2 Button switch/dimmer and a ikea bulb.

Both are added to SmartThings hub.
I have installed ABC. Tested with other items and installation works.

This is what I am trying to achieve.

  • pressing either button should toggle bulb on or off. On state should be latest used brightness.
  • holding either button should increase/decrease brighness

I can get on/off but not increase/decrease.

Can anyone help me out?
