cant open expert view for controller assignments in logic?

I just got a new m-audio axiom 49 midi keyboard and I am programming the controls to work on the keyboard. I got the transport controls done easily, but when I got to the faders and knobs, I had some difficulty. When I open controller assignments, it is stuck in easy view, and from the tutorial I've been reading from on how to assign the faders/knobs, you can have the controller assignment window in expert view which seems a lot easier(because honestly easy view was really confusing) 🙂
