It seems you selected to the top face of the staple to apply the Displacement BC. A better method of squeezing the staple against the fixed anvil would be to introduce another rigid body that would press on the top face of the staple. That second rigid body would have a Translational Joint to ground and a Joint Load of type Displacement to squeeze the staple. That would allow the staple to lift off the rigid body as the arm is bending. The displacement BC prevents the top face from moving out of plane which is not realistic.
