WARNING!!! PS3 trophies glitched

I beat all the challenges and times for the Single Player DLC but NONE of the following have unlocked:

Clock Watching (gold)
Time Attacked (silver)
Time For A Challenge (silver)

Other trophies have unlocked normally during progress. This is very strange.
I suspect the problem is that because of how I completed the challenges, these ALL
should have unlocked at once, but the game doesn't know how to stack unlocks?
No idea. If anyone has any advice I'm grateful. At the moment nothing I've done
seems to work. I'm reluctant to wipe all my save data to start fresh but that's
the only option I see left.
