Re: Missing Celebration Edition Content
Were you online ingame when this happened? Celebration Edition unlocked content only stays unlocked if you're online. If you get into the game without internet connection, you won't be able to access them.
However, if you were online and the skins weren't unlocked, then I suggest you reach EA Help directly. Several other users have pointed out here in AHQ that doing this solved the issue for them really fast.
I hope this solves your issue
