Inverted objects when exporting with Sandbox, glTF to babylon?

So Blender the blender exporter just made one mesh while exporting and the sandbox just made 8 meshes and the root node… idk how to change the exporting behavior so that the sandbox only exports one or blender makes 8.

I did some clean up and rename of my files so you may can better tell which is which. I renamed them so have that in mind that the playground file names have to be updated…
