Not picking up motion

I have a ring doorbell 2 and I have the sensitivity to max, I tell it to verify and I tell it to limit to people (as it refuses to stop picking up traffic). Now my mailman walks right up to the doorbell and it doesn’t trigger yet a car passing by on the street is 100% picked up?
