Lying still only means you are not producing engine,prop or waterflow noise. You could still emit ambient noise inside the boat that the escort hydrophone may be able to pick up. And being motionless does nothing to limit your ability to reflect active pings. Is your depth allowing you to be in the ASDIC vertical baffle zone? Well, apparently that is not modeled as such. Or it is shallower than you thought/history.
