Why won't my Vacuum Egg Lifter lift the eggs separately?

The Vacuum Egg Lifter was not designed to pick up 1 or 2 eggs.  It was designed to transport the amount of eggs whether 10 or 12 at a time. Push the egg cups onto the eggs, place your thumb on the hole to seal the suction, and transfer your eggs.  This device uses a manual vacuum seal to hold the eggs in place.
