No trophies showing up for Danger Zone ? Can anyone offer any solution to my problem ?? I've tried redownloading the application and still nothing

Hey guys got a small problem and would appreciate it any help. I bought a new game off the Playstation store, but for some reason when I start up the application it reads there are no trophies ? I'm signed into PSN and the game does have trophies but there not showing up at all in the list ? Don't know if it's just a bug or something ?
