When I explode a leader in Rhino 7.4, the Explode command makes new objects, but it does not delete the leader.
I cannot move the leader, I cannot delete it, and I cannot edit it. When I turn on control points, they cannot be moved with the Gumball. I cannot make any changes in the text either.
I have found the same bugs in DimRadius and DimOrdinate commands - these dimension objects cannot be deleted. I did not check other dimension commands.
