Remove flare gun , cannot be make it to work

[SCG_motoadve]

I shoot a flare and the gun stays in the cockpit.

I assigned remove flare gun key command via keyboard, and two different joysticks and in keymapping screen the commands work.

But in game they dont.

So once I shoot a flare I am stuck with the flare gun in the cockpit.

 

Any ideas how to fix this?
