Avada Google Map Not Showing when Minification enabled

I've added a map on this page: http://cartmell-solicitors.co.uk/locations/

The map is not showing when Hummingbird Minification is enabled. I've disabled "minification" and "combine" for all assets inside minification settings, still the map is not showing. But when I disable minification completely, the map shows.

How to fix this?

Support Access is enabled. I've temporarily disabled minification but feel free to enable it again while investigating this.
