Mashup Map element style pushing the map out of view.

We are using this plugin to display the locations of installed evacuator systems. each facility post (custom post type) has a map associated with it. On the main facilities page (category page) we are displaying a mashup map with all of facilities ( http://paddockevacuator.com/facilities/ ). The plugin and map worked great for quite sometime, but now we are having a CSS positioning issue. The third div inside of the generated map (id=map_1389884960251_preview) has an inline style of left:-12000px so the map is displayed 'off the page' and out of view. How can I remove this element.style so the map is displayed properly?
