Air brake binding doesn't work

[lax22]

After the most recent patch I'm not able to bind the F14 air brake to my HOTAS.

It shows a red exclamation mark in the menu even though there are no conflicts and when I try to deploy the air brake in game, it doesn't do anything.

Anybody else have this issue?

Hover mouse over the red mark to read what causes the conflict.

You can also make a backup of your controls and delete the files from /saved games/dcs/config/input/F-14
