Solved Divi map module "this page can't load google maps correctly"

I've followed all the suggested tips on how to fix this problem.
The main problem is that the api key is not even being attached at all to the javascript call.
there is a plugin for chrome that checks the maps api call, and it states that there is no key attached. (see screenshot)
we have an api key entered in to divi, it has been setup for billing, and enabled with all the types of uses.
the api key box shows correctly when viewing the module
the console has the error "Google Maps JavaScript API warning: NoApiKeys"
as you can see in the network log, the call to the google api does not contain a key either.

 

I have the latest wordpress and latest divi

I deactivated every plugin except divi exteded layout, and divi popup builder and still not working.

thats when I remembered the child theme...
I checked the functions file in the child theme folder and found a little function that was stripping out the query parameters. I don't know why that was there, but I commented out the one for javascript and then the query string appeared.
here's what it looked like
// remove query string
//
function _remove_script_version( $src ){
$parts = explode( '?', $src );
return $parts[0];
}
//add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );
add_filter( 'style_loader_src', '_remove_script_version', 15, 1 );
