Most likely you have more then 1 set of cockpits installed. Check your mods folder and make sure you dont have different versions installed if so try to minus one set out by placing a "-" minus symbol in front of the name then go back in game and see if that helped. I had this happen to me with the Bf-109's and I just had to deactivate a cockpit mod.
