Back when I had my Road Glide many moons ago, it had an anti-rollback switch in the return cable that would shut it off if you rolled back on the throttle like you're noting on your 2016. On that bike it was a common failure point. Most folks gave up and just unhooked that particular safety, as did I. Rostra does not have that capability that I know of (unless I fab up a custom switch assy and wire it into the brake or clutch circuit).
