Hi Nelsen,
Sorry for the late reply.
Will you please apply for fixed support instead of using displacement? For displacement can you provide constrain (displacement=0) to all the directions in your model? Are you performing the 2D analysis? 
I applied the fixed support to both sides of the flat surface or provided the displacement zero to all the directions on both flat surfaces and got the deformation of 25.9 µm. please apply the same BCs and let me know what you observed in that.
