Does the shaman enable auto attack but just not run up meaning it is getting the interact but not the click to move?

Are you driving from the shaman at the time? I think the default isboxer key map sets click to move at the start of the interact with target and then disables it after sending. Those tend to not send it to the current window which doesn't enable click to move.

If you are driving from the shaman, try enabling click to move and your interact with target should close then. Not sure if this is the best way to do it but it would help you isolate the problem.
