Drag and Drop not working.

What a shame, this installed so easily and appeared to be more functional than the other 6 combos I’ve tried.
You drag the icon to the other and it won’t drop. The circle with a line through it stays on. If you just let go there will be an error. The reset function doesn’t work either. Back to the drawing board.
