@robgrz Duplicate shares the defect that we reported wrt the Grouping Icon not refreshing when you ungroup items. If you Duplicate a grouped design element, the resulting element is grouped, however, if you click on the ungroup icon, the object ungroups but the mini-icon doesn’t reflect the change. Same is true for nested groupings…the system is doing the ungrouping properly, but not reflecting the icons.
UPDATE: The incorrect behavior is fully mimicked: If you try to group PASTED design elements, the icon is not properly updated to reflect what’s going on in the system.
