Solution:
User was using the "Post Type Order" plugin that was overriding the view's orderby option. Disabling the plugin "Post Type Order" helps resolving the issue.
Problem:
The user would like to display a map and marker inside an Elementor template
Solution:
The current Toolset-Elementor integration offers only a view widget. But we can still use shortcodes to insert a content template inside of an Elementor template:
[wpv-post-body view_template="Name or slug of the content template"]
Create a Toolset content template, add the map and the marker to it. Then display it inside Elementor using the wpv-post-body shortcode.
