Well, think about it this way, you initially created your emuNand as a clone from your sysNand, so in the beginning they obviously look the same.is my emunand supposed to have the same look as the sysnand? as in rows/theme?
But usually, as soon as you change it on one, it shouldn't change on the other. It might be the case if they are still linked but I doubt it's the case for you.
