These are a part of the exclusive anti-whoops feature included on all Endura Flap patio pet doors. If you mismeasured you might be able to salvage the situation by using the "anti-whoops" feature:

To make your panel about 1" taller, you may purchase a height extension (or create your own using a 1" piece of wood).

To make your panel slightly shorter, you may trim the flanges that accept the height extension with a metal hacksaw. 

If you need a substantially higher panel that doesn't fall into the standard Patio Pacific height adjustment ranges, then you may purchase a custom height Endura Flap‚ Sliding Glass Pet Door.
