[BUG] Unity 5.6 - Find Reference in scene

Hi,
I'm working on a project, with Unity 5.6, I didn't had any problem until I use Find Ref in scene on a material.
I expected that it would find every reference, but no... It just picked every mesh in my fbx :/

Do any of you may know why ? (It was working perfectly on an other project with 5.6)

I post 2 screens to show my problem :
