do you put a gasket both at the bottom of the center section ( as in your photos ) AND
on the inside surface of the bottom section ?
in this photo on amazon , looks like there's a gasket on the inside of the bottom section............near the rim. right ?

i'm guessing that is the least critical joint. meaning more air is going to leak out of the door and between the center section and the top.
