Hilti Profis - Anchors into Brick

When I run Hilti Profis into Brick with at a Concentrated Load and a line of 4 Adhesive Anchors the program only applies the Concentrated Load at the 2 middle Anchors. My Plate is Rigid so I am assuming that it should transfer the load to all 4 Anchors. Can you explain why it only is applied to the middle 2 Anchors? Is it due to the assumed strength of the 4" wide Brick by the program? Wayne Helmila with Rice Engineering Inc.
