I can't create maps with the Google Map’s [map id] shortcode using Betheme

Maps added using Google Maps’ shortcode are not working on my site with my current theme.

Google Maps shortcode is not working on pages when using the Betheme and it’s randomly working on event’s pages. For the events pages, sometimes map is visible for non logged in users, sometimes only for logged in and sometimes it’s just not visible.

I disabled all plugins and it didn't help, but changing to the WP2017 theme did help, although this isn't really a fix for us... we need to use the theme that we are currently using on our site.

Is there another way to pull in a map with a .kml overlay, but not using that shortcode?
