pivot painter hierarchy stop moving on foliage tool

So Pivot painter is super awesome and I love it, work good with grass, but I am now having a issue with the Hierarchy part of the script. The tree move accordingly in the viewport when I place the mesh.

Problem is when you paint the tree with the foliage tool, the strength of the branches is affected by the number of three place and after 10 tree it become still. I have tested with the Pivot painter Epic game content example map and the same thing happen.

Only the leaf part of the script stay unaffected by the number of tree ( bool static )
