Did you create your original location with the old classic app and before the Samsung account migration?
If so then I had the same issue myself. The first time I used there new app it created an additional default location. I guess it just looks to see if a location has been created by the new app / Samsung account and does not see the original default location when it does this. Ideally you use the IDE to make this new location non-default, but I suspect like me you can’t do this and both show as default. In this case you need to raise a support case and ask them to remove it.
