Was that actually changed because last I used the editor before the traits change you couldn't have a different folder name and girl name. Because believe me I tried and was one of, if not the first person to push for such a change. It's why you'll actually find a lot of the same girls with different versions use spaces to workaround the issue.
From what I remember your capitalisation thing is wrong for a start as on Windows, for example, it would simply merge a lower and uppercase folder. Zelda1, Zelda2, zelda3 would all be considered the same if you tried to also have zelda1, zelda2 and Zelda3.
