If you want to remove dark transparent layer from Google Map (SPPB addon), you have to use custom CSS code:

.sppb-addon-gmap::before {background: transparent !Important; }

OR

.sppb-addon-gmap::before {display: none;}

Above CSS code you have to use:

• In Page Options > Custom CSS
  OR
• In Template Custom code CSS area or custom.css file

You can also unlock more map features (for example zoom in/out) by DELETING that folder:
templates\shaper_hope\sppagebuilder\addons\gmap

But update SP Page Builder Pro 3.x before doing it. Or at least check if you have v.3.1.3 or later.
