User Relationship

I used pods to create a new user field ‘relation’ which allows users to have many to many relation between each other. My problem arises when i try to use it in gravity form registration. The pod feed mapping has these required fields wp object fields which requires user_login, user_pass, user_email. Why are these extra fields mandatory as i only want to use the relation field. (look image attached)

What i want: (I just want the current user to have a relation with the new account he is registering and vice versa. I already have a hidden field that takes current user id all i want pods to do is accept the value.)
