Pivot Painter 2.0 Parent index does not seem correct

I’m testing pivot painter 2.0 and it seems that my parent index values are incorrect. I have a tree with 4 layers of hierarchy and when i view the parent index i only see 2 layers.

When i set up the wind animation layers my 3rd and 4th layers animate around the pivot for layer 2.

I’m currently using 3DS Max 2019, could this be where my issues are coming from?
