Please provide any additional information below.
Just found it by mistake, by clicking on the target when I had actually no target.

Can't reproduce this error. Do you have any other addons interacting with the dressing room that might be interfering? If you click the button with no target, the action it takes is to just reset the current window (as if you had pushed the Reset button).
