My ring security starts countdown when you walk pass motion detector

This just started. I did put the system in a mode to chirp when there was motion but i turned it off. now when I put the system in home mode, if you walk pass the motion detector, it starts the countdown for someone entering the home, but the door is not opened. it never did this before so i must have done something when i changed the motion detections settings. I need help to stop this thing from going off just beause I go into the kitchen.
