JJWDesign Quick Radius function

i found that on my istance of SuiteCRM 7.1.5 [PHP 5.3.29]
the QuickRadius function doesn’t show anything but the default center.

Have you ever experience it?

I tried on Chrome and Firefox, in Italian and English Language.
No errors on Firebug nor on sugarcrm.log

Please liaise with the team at JJW maps. Have you tried in SuiteCRM 7.2.1?
