(M&M 3e) Adding new Advantages in Editor

[darkkoala]

I'm trying to add new Advantages (slightly modified versions of those from the 2nd Edition supplement, Mecha and Manga), but I must be doing something wrong, because they're not appearing on the list of Advantages when I make a new character. I've saved the user file and even made a duplicate version of the system to save them on, but even when I load that version, I'm not showing the Advantage I created on the list. I don't suppose anyone has created a tutorial for using the editor specifically for M&M?
