issue about changing name Fan page

Hello, I tried to change the name of fan page and the name of page was: Football News 24
and after I replaced new name: Football News TV
the name now is: Football News 24 (Football News TV)

and I don't know how to keep just the new name: Football News TV

thanks

It might take time before the changes can manifest. If it stays the same after 24 hours, try restarting your system and change the name again.

yeah it takes time to change
