grayed out options in controls page

[ralfidude]

Trying to set up my HOTAS for different buttons, and came across a few buttons that cannot be selected and are effectively grayed out.

 

For example I currently cannot select helmet mounted sights at all to set a joystick button to it. Gray all through the joystick, pedals, and throttle sections...

Do a clear category then it will work.
