2 Default Locations

[vseven]

I just had something very similar except the location I deleted did have all my devices. See if this might help:

I’m probably too late for this, but I also had the same issue. I would change the default location and it would not stay. Click on the email tab, there should be two of the same email showing up. Choose one of them and try again. If that doesn’t work, choose the other email and try again. It should then allow you to change the default and delete the empty location.
