How do I change my leader's diplomacy screen title?

I've been working on adding my own civilization to the game, and when I first started I used Catherine as a placeholder for my leader. I've got my own leader basically finished now, with no references to Catherine in the file, but when I meet them as another civ "the Great" still follows their name. I've looked through the XML files for text, diplomacy, and leaders, but I can't find that variable anywhere. How can I change it?

Edit: I tested it again and got a different title, so I'm guessing it's linked to your social policies. I just assumed that since my leader was based on Catherine that they got the title from her. My bad.

Yes, social policies.
