Pz.Kpfw. Churchill Ammo-load Bug

I was wondering why this tank is exploding after evry damn hit. Then i saw that the Pz.Kpfw. Churchill seems to have a ammo-load bug. I have loaded 45 shells only but all ammo-racks are fully loaded ingame with 80 shells. Just one tiny ammo-rack in the turret basket is empty. (Ready-rack?) Pls fix this!
