Trophies did not pop?!

[Sleezyskies]

So i recently finished all grand pix tournaments on expert difficulty and the related trophies did not pop. I then decide to head over to world tour and complete the last event on expert and the following trophies pop; Rank S, Sega all star and All Stars.

Has this happened to anyone?

I replayed the grand pix tournaments again and still the trophies do not pop though it says on my completion counter that i have beaten them. Is my game the problem r something r have i just hit a roadblock towards the platinum?

 

I appreciate any help, thnx in advance.
