Nokia C6-01 showing no Firmware Update, but Update Available

One day I was searching for the latest firmware available for the Nokia Smartphones. Every device seemed to be O.k with its latest available firmware installed other than mine. My Nokia C6-01 is still on the ver. 22.014 but the Nokia Mobile site as well as Software update site is showing ver 25.007 to be available. 

But when I checked for the update on my device or via Nokia Suite it says 'you have latest firmware already installed on your handset'. This is something very disgusting as Belle is already delayed and now I am not getting this update too.

Is there anyone else who's having the same problem? please report us in comments.
