Kangaroo SolidPointCollsion with cloth problem

Hi,

I try to do a cloth simulation with two stitched fabric pieces with an collision object inside. I can not get the collision working correctly. I don't know how to let them completely stay outside the sphere object. I tried it in both V5 and V6 with the same result. Here is the V6 file, because in V5 I have constantly problems with shatter component.

Many thanks for your help.
