Google Maps with API not showing up.

We are using WP Property on our WordPress site here: https://www.yourwhiteknight.com/properties/reno-cascade-3845-joy/. If you click the Maps button the map does not show up. We have added the Google Maps API that the client gave us and made sure the plugin is up to date but still can’t get the maps to show. Does anyone have any idea why it isn’t working?
