It appears we can use the “Duplicate” feature on tasks inside control points, but it’s grayed out and will not allow duplication of control points or control entities.
I’m not sure if it’s a bug, or a permissions issue, but we could do it freely in the last version (v9.4).
Addition to question above:
Is it expected that the control entity or control point you’ve clicked on does not highlight or give any indication as to which one you’ve clicked other than down at the bottom? Again, all previous versions did.
