How do i set my avatar to default?

My RDR avatar award has disappeared?

• I've been playing RDR for a while now, and thus far have never played while being connected to the internet(figure I'd mention). While I was raiding that white building in the beginning of the game, that place where you go in and a guy has a woman at gunpoint on the ground and you must dead-eye him(Although I believe I didn't have dead eye yet), I accidentally shot someone's hat off his head, earning the avatar award for the sombrero. Now, although the avatar award clearly states that I must be in Expert Aim mode while shooting someone's hat off their head, to my amazement and confusion, although in regular aim mode(aim assist, the one that's set on default when starting a game), It still notified me I earned the avatar award and was awarded the sombrero. I saved it to my outfits with that trench coat(In the "dress-up" section or whatever). Now, a few weeks later, I connect my xbox to internet(hadn't played for that few weeks), I go to my avatar awards, and yet again to my confusion, the only avatar awards I have are Halo Waypoint and Left 4 Dead 2. Red Dead Redemption isn't even in the list. Just Halo and L4D2. So I go to my saved outfits, and there it is, my trench coat and sombrero outfit, but it is grayed out and when I press A(Xbox 360 by the way), nothing happens. So I go into Settings>Memory>Avatar Items and actually FIND the sombrero. Its right there, in my hard drive. So, can anyone explain what the hell happened, and how do I fix this?

• Answer:

  RDR achievements are known to glitch. It would be best if you went to the rockstar forums and ask them what to do.
