Shadow matte problem?

self-shadow-problem.pngI have a problem with my shadow matte on my ground shader. I created a scene with grass and a ground. I want to have the shadow of my grass on my ground using the shadow matte procedure. To do so, I added to my ground a shadow matte, unchecked the selfshadow box and I put my grass in the Forced phantom box of my Arnold Render, but when I'm rendering, the ground looks like it receives shadow of itself and I shadow that I should not see. In the red circle in the image below, there are ground details that should be invisible. How can I fix it?

Thanks.
