chaned name, have the same name in launcher, cannot get in hypixel?

Hi, If maybe one of you have this problem when changing name you should read this.
My name was BotEuro before i changed it, I changed it to Eurx. In the minecraft profile website it shows i changed it successfully. When i go in the launcher i get confused and i have my old name in buttom right corner. So i launch the game, I can play singleplayer. But i cannot join hypixel and other servers.
