Can't map 'clickable mouse cockpit" all of the sudden

[dresoccer4]

For most of my modules I have "clickable mouse cockpit' mapped to my 'mouse button 3'. However with the Corsair, as you can see in the screenshot it's greyed out and I can't map anything.

Anyone know how to fix this?

yeah I gave up on that and just made it "M"
