GroupActors Lose All Property Values on Duplicate/Copy-Paste in Editor

Duplicating a Group (whether through Alt-Dragging or copy/pasting) does not carry over any property set in the source Group actors to the duplicated ones. Additionally, with Alt-Dragging, the duplicated group does not follow the axis they are duplicating on. 

1. Open any project in a level editor, sample Third Person project for instance
2. Change to Local Space gizmos
3. Multi-select a few actors
4. Group them
5. Rotate them
6. Alt Drag on any translation axis
7. Observe that duplicated group does not follow axis we're duplicating along
