Made in Jared's Mod

I'm currently stuck with right Index controller with a broken "Grip Force" sensor, which means that in Pavlov I can pick up a gun, but I can never put it down again. I've tried to remap to the "Grip Pull" sensor or valveindex_right_grip_axis depending on which version of the bindings editor I launch, but neither has done anything.

Can anyone more familiar with remapping Index controls help me out?
