Clan name change...

Hi... im having a problem with Clan name changing...
I bought it from the Mall and used it... but the name changed in the game but in the website the Clan name hasnt changed... im not sure if you would understand.
For example, My first clan name was []**uPz**[] but i changed it to -[M]is[T]*
In the game it says that i am in the clan -[M]is[T]* but in the website, if i click on :
"My Clan", it says that im in []**uPz**[]. Please Help~ (
