FSX Steam and ADE 1.78

[Speedbyrd]

Hi,

I'm running ADE 1.78 with FSX Steam and all works fine for the most part but some of the scenery objects don't show when I add them to an airport. Static planes, some vehicles and blimps, balloons don't always show up. They show on the library object list in ADE but not always in the airport scenery. Any ideas on this? Thanks
