FF5 Character Names

The thing is I try to change the character names using FF5e text Editor 1.6 & Everything's FF6Tools, but no effect in the actual game. All the other things can be changed by these programs, such as Job names or monster names, but the character names in the menu stay the same for some strange reason, even after changing them by the editor. I'd like to change Cara to Krile in the menu, does anyone know how to do it?
