Having this incorrectly set results in the shifting plunger not being in the correct location, which results in the balls not being on the round OD of the plunger, and rather the ramp edge, enough to "ratchet" as you're seeing.
Feel free to email me at prosupport.

It was in fact the piston coupler. It looks like someone tightened it way too much and the piston end started to open up. I put a new one on and the robot stops and turns great now. Thank you for the help.
