Auto unlock feature odd behavior

On first setup, the auto unlock feature worked well.
When I get within around 50", my phone dings and the lock unlocks. Open the door, close it, and it auto locks at the 30 seconds I set.

Yesterday it started acting odd. When I get within 50" or so, I receive a bevy of app pushes to my phone, about 5-6. They all come in at once so it sounds like more but it was just 5 as shown in the screenshot (the first message is from another door).
One message shows the mac address and two characters.
I did the Bluetooth firmware update today and that didn’t change or fix this behavior.
