Relationships with relabelled modules SCRM 8

I have a “Loans” custom module that has a 1 (Loan):many relationship with my “Accounts” module which when I created the relationship I changed the “Accounts” label to “Borrowers”. I now want to create a many:many relationship between my “Borrowers” module and my “Contacts” module and relabel the Contacts side “Directors”. How do I form the relationship with the “Borrowers” module as all I seem to be able to do is form a relationship with the “Accounts” module again?
