Tinkering with Controls

So since the newest update erased a bunch of stuff, I was going into the controls option when I ran into a problem. When selecting steering, the game won't let me scroll down to save my preferred inputs. What should I do?

 

I got it to expand, sort of, by kind of clicking around the area that shows the input movement of the analog stick. Not sure if the mouse clicks or the movement of the stick made it focus.
