I think I have fixed most of this. The reason you have a shoe and the release is "sticky" is that I have designed this so the controller is the ball and the other controller is a shoe (foot). I added a toggle on the settings screen for the controller-addicted people to bowl. The shoe (when the controller is tied to a foot) will trigger the foul light and haptics.
I'll upload my newest in a few minutes. still working on gaze interaction with the settings menu since the controllers are really intended to be tracked objects.
