resistance and breakage damage (NieR: Automata)

why doesn't the open damage the chip if the chip on resistance. and sustainability are weird, I shot the robot in the arena Sands, health I was just over 40% and still I was pushed off a rock on the ground. Yes, and this shit stops working breakage damage. and even characters such control is twitchy, she is does not stand still, a pain in the ass, and the stones jump.
well the resistance is working, checked these flying saucers Gresko couldn't knock the stone on the ground, but breakage damage not fucking plows together with stability. that is why no where it is written, it may glitch?
