Content Fragment Model editor is showing empty when we create content fragment model from child configuration
When we create child configuration under another configuration in configuration browser and enabled content fragment models option, I am able to create content fragment model. But model is not showing options to add fields by drag and drop. It is empty when we try to edit.
Same is working fine if we create content fragment model from normal configuration. This is working fine in 6.5 but not in 6.5.10 and 6.5.12. Please suggest.
Child configuration is allowed as part of this doc- https://experienceleague.adobe.com/docs/experience-manager-64/administering/introduction/configurations.html?lang=en
