Preview multiple locations on map

Add a company with multiple locations;

Previewing a place with one location works fine, but when I want to preview a place with multiple locations (similar to google maps), the map does not show markers at all. The data is not yet saved so only custom state is used. I have zero issues and everything looks fine what I can see, but since it is not working I am missing something. This is in a pop up. What am I missing?

Example google maps showing a company with multiple locations:

It works fine with one address and marker, but multiple locations is needed to be shown sometimes.
