I cannot reproduce the problem, see here:
We surely haven't added any objects at MYNN but, fact if happens there is a bit suspicious, since it's the airport used as a sample for the SDK.
It's possible another scenery you installed in the Community folder is derived in some way from the SDK sample, and like the sample has a file named like this:
scenery\global\scenery\modelLib.bgl
Like the sample, but this is likely causing a conflict, since there might be several sceneries with the same path and name and this has been confirmed by Asobo is a mistake and it will surely create a conflict.
Our KEWY has the model lib .BGL named as such, to prevent any conflicts:
scenery\FSDT_KEYW\scenery\Simultech-KEYW_modelLib.BGL
Just be sure to run the FSDT Live Update, because I think the very first release ( before this problem was known ), our .BGL was also named modelLib.BGL, but we fixed it shortly thereafter.
