The graphs look basically ok.
How does it look in the viewport?
You said you can move the mesh there, can you also use the material overrie? Does it change appearance?
When you select an instance of the BP from the level in the BP editor for debugging, does the graph execute completetly?
I created them in 3dsMax, unwrapped them and exported them as FBX. The origin of the meshes is their center.
The material rather simple.
The master material looks like this:
And for the instances you can just make changes…
So, Im also curious to find out what is not going right in your BPs.
Keep me updated 
Cheers,
