Store Locator Addon Problem

In Addons > Store locator trying to set coordinates, getting this
Oops! Something went wrong.
This page didn't load Google Maps correctly. See the JavaScript console for technical details.
In front end map works...
cs-cart 4.3.7

So what do you see in the console?

Google Maps API error: MissingKeyMapError
Google Maps API warning: NoApiKeys


[!] Add-ons: Store locator: Google Maps API key wasn't used. Fixed.

Hm since when key was not used ..?

Ask CS-Cart to provide you with the fix
