Cannot query the AnimationController's layers or states when loaded in assetbundle

Hi
Our AR app loads its content in using assetbundles.
The content comes in with animation, with is working really nice.
the only problem is, I can't query the layers/states of this animation

I have set up a test scene, with the same animated content but not loaded using an assetbundle
I can see the statemachine graph and can query all the layers and states
but in my production scene, where its an assetbundle the editor looks quite different

please see the attached images which compare me using pretty much the same query code for the 2 different scenes

any help much appreciated, not much coming up on google for this.
cheers
Tom

 

Im looking into the fact that this is an IOS bundle being viewed on macOS in the editor, hoping thats it...

 

OK, so I build a standalone OSX assetbundle (assuming this is what mac OS should load up ideally)
it made my asset's shaders look not pink, but all the problems listed above are still true
