SkeletalMesh doesn't Attach to Mesh in Player Controller

I just finished creating a Character with animations and when i Created a Character Blue Print My Skeletal Mesh doesn’t want to connected or get recognized by the Skeletal Mesh Section in Character controller.

Is it a problem with the Skeletal mesh or a bug with the Engine itself?
This image also tells my problem:
