dishwasher bottom seal repacment?

Hi, We have a De Dietrich VZ9946U1 And it has been leaking from the bottom of the door so i ordered a genuine bottom seal to fix this. When i removed the front cover i noticed where the seal was fitted to the door did not seem right so it looks like someone has put this on incorrectly. Can you help me to find out where this seal actully goes? Kind Regards Malky
