I'm not sure what you are talking about. I just deleted all the modules from PC and loaded the CA-2A where it went below the quad EQ but all I did was grab the module and place on top of the EQ. Now if you are complaining that there is empty space above the module because there is only 2 modules I can't see a point in that complaint.
The idea is being able to route signals through modules in an order of one's choosing. If you only need one module loaded beyond the EQ worrying about empty space is ridiculous. If you are concerned about clutter as you put it hit I on your keyboard.
