Studio theme and Google Maps issue

I am trying to display Google based maps on my site with Studio theme installed but the popup infowindow for the map marker icons is being corrupted.

Map page link on Studio theme: http://thegallerieslist.com/glocscode4/

I have the same map system on another site with Blogs MU and no issues at all.

Any clues as to why this might be happening would be a real help.
