Detach instance data to USER elements - ABD CONNECT UPG2

Hi there, I'm trying to Detach instance data on a beam created from a solid, using the Detach tool but it deletes Family and Part info but doesn't delete Datagroup name and catalog. I can see it in the Building Element Info dialog.

Process: I first created the solid (curved "beam"), then I used Attach tool convert it into a catalog beam with Datagroup info, and when I want to modify datagroup data I cannot do it because "the element already has instance data".

1.- How can I delete ALL instance data from an element created this way?

2.- How can I apply Datagroup data from an element to my "USER" element?. Using Schedules only works with APP elements, not with USER elements.

Thank you
