Updated Blender 3d Object not importing into the SDK project [not showing up as completed gltf in the 'Build Project' Console

Any idea why a 3D object [a hangar] i updated in blender, is not importing correctly in the SDK ? I have the right modellib folder ,and the three files in it [ bin/gltf/xml files] like i always have before.

I have updated this building multiple times before, but this time it is not showing up in the SDK project. All i see is the older version of this building.

The ‘build project’ console does not show this gltf either.

There is an error in the Console that says ’ failed to load gltf-lister’
