How to change my admin name?

So on my mac, I have changed all my names to the same thing, but when I go to open a folder it still appears as "JohnSmith". How can I change this? I already changed the settings(screenshots below) everything else that has my name right just not in finder.

But my folders in finder still say "johnsmith"
