Dishwasher leaking

Samsung DW80R5060US dishwasher is leaking. The seal at the bottom of the door on the inside has disintegrated. THIS IS NOT THE TUB SEAL. This would be the 4th side the tub seal does not cover. Can someone please tell me what part this would be?

The only way to get the lower door seal will be to get the inner door panel. Here is a link for the part. DD81-02055A Dishwasher Front Tub Assembly | Genuine Samsung OEM In Stock
