This is a little strange but I think that the reason could be an invalid coordinate address. Maybe the Google's maps API not returns the correct coordinate. In fact, if you inspect the map near the Greece you can find a sinister Korea, Republic of.
If you try to inspect the result of the Google's API request launched by Phone Home, that is:
https://maps.googleapis.com/maps/api/js/GeocodeService.Search?4sKorea%2C%20Republic%20of&7sUS&9sen&callback=_xdc_._s9jkcc&token=64929
you can find something like that:
... "geometry" : { "location" : { "lat" : 37.984654, "lng" : 23.760616 }, "location_type" : "APPROXIMATE", "viewport" : { "northeast" : { "lat" : 37.9860029802915, "lng" : 23.7619649802915 }, "southwest" : { "lat" : 37.9833050197085, "lng" : 23.7592670197085 } } }, ...
But if you try to insert the coordinate in the Google maps, the point is in Peloponneso not in Korea , the real coordinate is:
lat: 37.9833050197085 lng: 127.7619649802915
Google, this time you failed.
