Car charger not marking location

I just bought the car charger/finder but for some reason it doesn’t mark where my car is parked. But does show the car mileage. I use an iPhone Xr

I’m a long time user of the charger/car finder device and It has performed flawlessly until I recently downloaded an update from ZUS and now it doesn’t record my parking location properly. Hopefully ZUS is aware of problem and a fix will be downloaded shortly.
