Hi Kevin, This is due to bug 4475966.
If Group is use as an arming Node, BOUNDS is always used. In the case of USE_GEOMETRY, we should search the scene graph recursively to found Shape3D/Morph under the arming Group node and check the intersection with them. To workaround the bug, do not use Group as an arming node, use Shape3D/Morph under the Group instead. Note that utility shape Sphere/Cylinder extends Group instead of Shape3D.
