App name updated but not on GameCenter

I'm having a quite simple problem, but i hadn't found any solution. I updated my apps name in the AppStore a few weeks ago and just a few days ago i saw that in the GameCenter it didn't change.

Is it something i have to change or should i get in contact with the Apple Support?

Get a look:

Name changed in the iTunes Connect correctly

Same old name of the app

Solution

I had this same problem with an app I was doing work on. What I found was that when I updated the app a second time, the name changed in GameCenter.
