Physics Torque Bounce Bug

I’m trying to roll a perfect sphere using a collision sphere by applying torque. At random times, the sphere bounces up unexpectedly. This should not happen. Not sure how to solve this.

The issue was apparently using multiple collision boxes for the mesh. Even though they lined up perfectly, the physics system had an issue with it and interpreted it as a “bump”. The solution was to use a single collision mesh for the object. The bounce happened at collision box boundaries. This seems to be a bug?
