One-way implied relationships (father->son)

Hi

I've just installed this module. I've read all documentation in drupal and module, and I've not found a simple way to create some type of relation. Now I think that it can be done, but it's hard to do.

If we set a implies such as "father" and "son", i go to my son profile and put "son" as relation, in son pending relation we found that I can be son or father. It should only show that I'm his father and accept it or not.

Now also if my soon check father, if I go to my relation, in both "father" is the relation, and I've multiple relationship disabled and "father" and "son" are "one way" (I've checked alto all possible options). So I think that's a bug. If I'm wrong, please, how it must be done?.

Thanks
