IBeacon issue. Do I have the Companion App configured incorrectly?

I’m getting multiple devices for the UUID of my Android Companion app. I just started using iBeacons, with the goal of just using it as an overall device tracker to see if I am home (along with GPS and wifi). But the device for the device_tracker keeps changing.

Do I have something configured wrong that is making the app send a new device with four random alphanumeric characters at the end (like 3E24)?

no the tracker reports everything it sees

Why is it seeing all of these devices with the same UUID, but random characters at the end? What am I missing?
