If a section with MB Group Skin's elementor widget, all dynamic tags went missing. If I remove the widget and refresh the editor, all dynamic tags will shown again. Kindly refer the attached video https://www.youtube.com/watch?v=706JGSVRjv8.
It is expected behavior. If the template is assigned to the type "Meta Box Group Skin", you should create the template for the subfields in a group only. Then you can add the Meta Box Group widget to other templates.
