How do i change what the url box says in my band's myspace?

everyone said i couldn't change a myspace url and i did it, so please don't answer me with "you can't"

when i change the url the little url box in my profile still says the old url but the old one isn't correct.

the new one works.

how do i get the little box in my profile to display the right thing?
