Nickname change

Darleen • God first! Due with a beautiful baby girl September 30th, 2015! So in love already!👨‍👩‍👧
So I changed my babies nickname and gender on the menu and for some reason it still says the same thing! When I go back to change it again though, it has what I changed it to, so no problem there. 
Just doesn't change on the screen where it's supposed to! Help? 😳
