Business Corporate with UPM User Location Widget

With the other themes there is no problem but with this theme there seems to be a conflict with using this widget.
I am trying to use it in the buddypress right sidebar.

The map is showing but only a very thin line. Possible css issue and I need to add some code to my child theme?

Hope someone has an idea to try as I think that this theme is the right one for my site.

Regards
Mark
