Gravity Geolocation bug - disable the address output

Unable to get any support via Home - Gravity Geolocation

All I need to do is disable the address output from the map, so when the marker is moved the address field does not change. This is a feature of the plugin, but its not working.

Any ideas welcome.

When the option is enabled on the geocoder field, when the map marker is moved, the value in the address field is wiped, where of course it should remain unchanged.
