Ok, I tried this:
Starting up the editor, I double clicked the Loop 2 button, set mode to Hold, then switched over to the hold function tab and set the button type to Device PC+. Then I clicked Done. The button is now shows "Loop 2 / Device PC+".
Next I, clicked the button, did a copy, then selected a different button (Loop 5), and pasted. That worked as well.
Does this work for you if you try the same?
