Multiple Face effects in editor share the same expression

Hi, I’m using this template Face Effects to create multiple face-meshes and the positions of the anchors are correct, but all face meshes share the same expression and are deformed like if they were trying to adjust as if they were the same.

For example, one person opens it’s mouth and all three meshes do the same even if the other two keep their mouths closed.

In this photo one has the mouth open but both have the mouth closed and curved, and the meshes are in the same angle.
