Google Maps not picking coords from database

WIX newbie here, but lots of engineering experience in my working days.

Trying to build a website that displays camping sites. Found a real estate template that works up well. Having a problem with Google Maps picking up the GPS coordinates from my database, though.

Maps appears to be connected to the proper database item, but nothing gets displayed. Note: I temporarily added a 2nd map to the page and it has the same problem.

Any tips?

Thanks, Ralph
