Distance in the shadows of the sprites and quads.

Hello,

I'm still experimenting with shadows of unity pro free trial and I've noticed that the sprites and quads do not cast shadows well. They are spaced so that the shadow and the quad are always separated by much lower the quad or sprite. Pictures are better than me explain:

Is there any way to fix that? So the shadow is completely attached to the sprite or quad when it is in contact with the surface that receives the shadow. The bias is 0.

Thank you.
