Raised deck in wall cabinets. Why stile behavior?

[GeneDavis]

My go-to detail for wall cabs is to raise the deck (bottom) 1-1/4", overhang the door the same as the raise, pin a 1-1/8" light rail behind the door up against the deck, all this done readily with the frameless schemes I draw, and exposed ends ("gables" in cab-speak) get their bottoms extended 1-1/4" to match the doors at fronts.

 

From my CAD detail library, here is a section showing the detail.

 

 

In a run of two or more boxes with exposed ends, only the end gables get the extension.  In the plan attached, a run of three cabs is modeled, and I want to know why the center box has voids at the front edge of the sides.  This particular model has applied panels on the exposed ends, but the behavior is there whether or not the ends are paneled.

 

 

End box right.

 

 

Center box with voids at R and L front side edges.
