Tell us what you are trying to do? I am trying to use a view to display a related post data (address) as a rendered marker inside of a single map.
Is there any documentation that you are following? I've referenced the documentation for Maps.
Is there a similar example that we can see? hidden link
What is the link to your site?
Can you try to insert that View to a Page not using Elementor widget, and check if it still outputs 2 maps?
If so, then in the view loop must be more than one Map ShortCode.
Otherwise, this will be an issue in the template made with Elementor where the Elementor Widget displays this view.
I think the issue here is that in Elementor a Map is inserted as a standalone Map (as single element), and IN the view loop, there is another map
If this is the case - remove the map not required so to solve the issue.
