Pivot Painter 2 some sections disconnected at pivot point

I’m experiencing an issue with some higher branches getting disconnected when using a custom texture created with PivotPainter2 in Blender. I’m following the UE PP2 example and replacing the texture in the instance of the branch material, with the texture set as a VectorDisplacementMap. What could be the cause of this disconnection, and are there any potential solutions to resolve this issue?
