Auto unlock/auto lock

I am using the Auto Unlock and the auto lock with the door sensor. The issue that I’m having is when I arrive home the door unlocks like it’s supposed to but then the door sensor shows the door as being closed and locks the door. I can disconnect the door sensor but then the door will lock and extend the deadbolt even if it’s open.

How do you disconnect the sensor? I’m having a bunch of issues with mine and can’t figure out a way to disconnect/unpair it.
