Well that means Either your ddress fields correspondancy is mistaken, or The Jomsocial core Geocoder doesn't work wich can happen depending on some hosts.
You can use the Profile plugin for Jomsocial you got in the Geommunty package (Geommunity Geolocator) to let users click on their profile map to update coordinates. to test.
We also have a powerfull Geocoder for Jomsocial you may use. it requires fields to be set correctly too, but falls back to Yahoo Geocoding if Google fails. This is an additional addon, not included in Geommunity core package. Most Jomsocial sites don't need it.
