How to make the Buyer Relationship Map functional?

I have enabled the Buyer Relationship Map on the Standard Account Plan functionality, added the Buyer Attributes, Department Group, and Seniority Level  fields to the Contacts page and created a contact on the Account. My profile has access to the 3 fields.  Still the  Map is not editable on the Account Plan and displays more as an image?. How to make it functional?  input on this would be helpful. Thanks!
