Problem Displaying multiple maps one page

Using wp-google maps pro on this page http://oregunbst.com/ffl-locator/ using visual composer to create the page with accordions holding different maps. not sure if the problem is with the theme or the plugin. i’ve never ran into this issues with the map plugin before. but only one map with load unless you refresh the page with the map you want to view open, or if you resize the page it then shows.

any ideas?
