Broken achievement?

I realized after reviewing my achievements I've noticed in the game Band Hero I didn't receive a really big gamerscore of 490 for unlocking all of the secret notes in the game.

The Achievement is called Treasure Hunter  for 490G

description: Collect all the Secret Notes

 

I've already collected all the secret notes but I never got the achievement to pop up.

Is there any way xbox can just quickly fix this glitched achievement?

If that achievement still isn't unlocking, you may want to try recovering your Gamertag, and then earning it again.

Did this solve your problem?

Sorry this didn't help.

Great! Thanks for marking this as the answer.
