Shading Small-scaled models in Unity

Hey,

I'm new with Unity and have had issues with certain objects in my Hololens App.
I'm dynamically loading models into the app and rendering them in front of the user.
The objects are scaled down to fit onto a floating platform.
Certain objects don't have the right shading after doing this.
The object has the correct material when I look at the Inspector tab.
When I scale the object up, the object looks fine.

I'm using the StandardFast shader from the HoloToolkit.
Is there a way to work around this?

Thanks!
