The application.xml file has repeated rows

I am trying to configure a newly installed Jazz Team Server's LDAP connection.

I haven't succeeded yet but one of the things you are told to do in these instructions  https://jazz.net/wiki/bin/view/Deployment/ConfigureLDAPforLibertyProfile  is modify your application.xml file with the group memberships similar to the group mappings in the JTS Setup (LDAP Part 1).

The Group names I am using  don't differ from the default so I don't think I have to edit this file.
I am using "JazzAdmins", "JazzProjectAdmins" etc.

But I do have repeated rows in "application.xml" for the group names.

Does this matter ?

Thanks
