Trying to get the "Default" empire's shipsets to work

Hello everyone:
I need some help. I was looking through the Empires folder and I saw an empire named "Default". I was looking through it and I liked the shipset it used. I tried modifying the settings.txt on the line "Number of Quick Start Styles" to 15 and added another line in the empires line to include the "Default" empire. I started a new game and went to quick start and tried to create a new empire but I could not see the shipset there for my choices.

Did I do something wrong?

I apologize if this question was asked before, I tried doing a search but I only found information about installing new shipsets.
