Why haven't my trophies in Uncharted: Drake's Fortune appeared even though I finished it?

I don’t know why my trophies haven’t shown up. I mean, at the end of the day it’s no big deal, but I just wonder if there’s some kind of error/glitch or something I didn’t do. I finished the game a while ago and noticed that, even though trophies have popped up while I played the game and finished it, nothing has shown up on my official list. It still shows 0%, as if I haven’t played the game.

This is on the PS3 btw, in case you haven’t realized.
