Hey,
Thanks for reaching out to us and I apologize for any inconveniences you’re experiencing in using our plugin.
Unfortunately there isn’t a whole lot of support that we can provide for theme conflicts such as this. For this, it sounds like the theme has a google maps shortcode? If so, it looks like the google maps API is being called even if the shortcode isn’t used on the page.
The best way to approach this would be to have the theme only load the necessary resources when the shortcode is used. Here is a great article describing how this can be accomplished http://mikejolley.com/2013/12/sensible-script-enqueuing-shortcodes/.
Thanks!
