Google Maps not identifying our location correctly

I am using the google maps plugin, when I type in our address information, it doesnt pull up the correct address. I move the bubble to our location, but when you select "get directions" from the front end, it gives directions to the wrong location. I have tried entering our address several different ways, but all give the wrong location. When I go to http://www.googlemaps.com and type in our address it yields the correct address.
