Alter requestee_list_link or requestor_list_link

I don't know if this is something I've caused by changing some settings or if other people have noticed it but on my site relationships/list doesn't exist. This wouldn't be a problem but the default emails sending out requestee_list_link or requestor_list_link are formatting with the relationships/list in the links it creates and sends.

So whenever a user clicks a link they get a page not found. The links are formatted like :

http://www.48fourteen.com/user/100/relationships

on the actual site. The emails, however, send:

http://www.48fourteen.com/user/100/relationships/list

If I've changed some settings then I can change that instead of dealing with the replacement patterns but if there is no such way to change the settings like that then I will have to change the patterns and make sure it starts sending out the correct links.

Any advice?
