No stress at outside bolt location?

Hi, when I'm doing a doing a static simulation of the stresses near the bolt, I get some weird results.

I used SW standard definition of a bolt and nut. Preload Axial force of 5.12 Newtons. No Penetration contact.

The force applied is directly onto the beam. Here's a top view of the walls and beam

The area I'm concerned about is the bolt location. As you can see below, there seems to be no stress on the outside of the wall.

On the inside it looks fine.

Not sure why there would be no stresses on the outside. Any ideas why or what went wrong (I'm sure my initial conditions were all fine).
