Unable to unmap controller inputs for drone

There does not appear to be a way to unmap controller inputs for the drone. The game thinks my VKB Gladiator EVO is a Controller(I play with a Joystick that I have mapped keys to to control movement, jumping reloading etc due to physical limitation of not being able to bend my fingers so I am unable to use a keyboard to play).  Before I unmapped the controller buttons and joysticks from infantry i would just spin in circles when I join a game.  unmapping the controller inputs fixes this just fine but there does not seem to be a place where I can unmap the controller inputs for the drone.. I am in the campaign mode playing Operation Emberstrike where i need to use a drone and it just spins.  Is there any workaround for this?  Were controller input mapping left out by mistake?  I have unmapped the controller inputs for everything(infantry, vehicles, aircraft, helicopters, gunners, transports) and am stuck on this.
