Is my Alpha One/Alpha Two Chain Guard Broken?

The plastic chain guard that comes with the Alpha One and Alpha Two has a cut out in the back that can appear to be a break.

The arrow in the above picture points to the cut out on the Alpha Two chain guard.  Note that the Alpha One chain guard is shorter and the cut out is slightly different.

The purpose of this cutout is to allow the chain guard to tightly fit around the rear stays.
