Contact Pair for Structural Mechanics

Hello everyone,
I am trying to model a sphere pushing into a corner. To do so, I have created a 2D model with a load. Since the two surfaces will be tangent to the sphere surface, I use contact pair to handle the point contact issue. However, the model does not work and the two parts penetrate into each other, which is shown in the attached picture. I defined the contact pair under the the model's definition and solid mechanics. Does anyone know why this happens? I thought maybe this is a common problem that might root in a simple mistake in defining the contact.
Thank you

It could be that you are scaling the displacements in this plot, especially since the stresses are very small. Making sure displacement scaling is off (scaling factor =1.0).
