LG Washer leaking from door boot

I have a customer that has an LG front load washer and you can clearly see water coming down the front at the bottom. She took it upon herself to order the part and had me install it. Testing it went fine, no leaks, but put cloths in it and it opens up at the bottom again and leaks. There is a marked difference between the two gaskets where they meet the door glass at the bottom, which accounts for it passing the initial test. but she got the old part number, I understand there is a new part number out there but is on back order.

Has anyone come across this one before? Why did they change part numbers? could it be the hinges?
