Prior to Windows 10 Annivesary Update. Cargo Loaders aligned with Back Cargo Door on this Aircraft. Since update I get 2 cargo loaders but neither aligns. They align more to centre of aircraft where no doors exist at all. On Just flight B757-300 without wingtips I always get one cargo loader perfectly aligned to back cargo door. Never been able to get 2 Cargo Loaders on this particular series of aircraft. Any ideas how to correct this would be appreciated.
