Leaking dishwasher - LG ldf7810st

I have an LG ldf7810st dishwasher that’s leaking from the bottom. I’ve already replaced the main seal around the tub (3920DD3005A). The leak is intermittent (about once a week) and seems to be coming from the bottom of the door as opposed to from under the dishwasher.

I took the front of the door off and there’s another seal/gasket at the bottom of the door that’s all warped with some corrosion of the metal around parts of it. When I feel for the seal from the inside between the tub and the door, in some places it bulges out into the dishwasher and other places it goes in towards the door.

Which way is this seal supposed to go, any idea on how to replace it, and what part number is it (3920DD3002A?) I can’t figure out how it attaches to remove/replace it.

Also, any other things to check for leaking?

Thanks in advance for your help.
