This is not a long term fix, but if I import that file to blender and then export again, it works for me. There must be something in the 3DS max export that is not supported yet in the addon (can you plz make sure that exports from 3ds max, don't have compression or other more advanced gltf features enabled?)
Can you also please send the gltf (not glb) version (w/ embedded textures), easier to read the text format.
Here is the file that worked for me after processing it through blender (I did have to increase scale):

Another note: it seems to be something to do with the separate objects (e.g. legs and cone) are being thought of as one connected mesh. Something in the blender processing, separates them into separate objects which are not connected, reviewing.
