Rhino 8 Duplicate Layers Selection Staggers

I’ve noticed something strange happening in my larger Rhino 8 sessions when it comes to duplicating multiple layers at once. Here’s an example:

  1. Select two adjacent layers:

  1. Right click on one of them and select “Duplicate Layers and Objects”. This is the expected layer selection result afterwards (both copy layers are now selected):

3 However, often times this is what happens instead with the layer selection result afterwards (one of the copy layers and one of the source layers are now selected):


Needless to say this is definitely an undesirable result. Normally as soon as I duplicate layers I drag them to where they need to be, but this selection glitch completely screws that up. If I dupe, undo, dupe, undo, dupe, etc. 10x times in a row, then this selection glitch happens 5x times.
