Another way of fixing this prob would be:
Drag the All Kill Icon from your macro-gump into your hotbar at the bottom of the screen (or any floating hotbar). Then right-click it and a little context-menue should open. Now, when you hover your cursor over "Target" it should open another little list with the options "current", "cursor" or "self". There you select either cursor oder current, as you like best.
having done this, you right-click again and simply define a hotkey for it.
... and you're done
