Custom Airport Positions - error

[CaptainGabe]

Hello all! I recently upgraded my PC and lost my previous customization (previously done on ADE via the bgl.)

I decided to use the one provided with GSXbut every time I enter to edit the position, I get the following errors...See images.

Please help! I am trying to make the positions as accurate as possible to real world.
Thank you!

Which airplane you used ? From the error code, it seems you are using a unsupported plane with no configuration, and without a main passenger door.

Makes sense, narrowed it down to a cargo position error and your reply clarifies it.
Thank you!
