My play time isn't being updated for my games. Why?

Ever since last week, my ps account has stopped updating both my play time \*and\* new games ive played. I thought maybe it was just for one game, that being Resident Evil: Code Veronica, but i've since gone back to other games and their hours aren't being logged either. In fact, my "last played" hasn't updated in six days.

Is anyone else experiencing this problem? Is it something I can fix? Not the end of the world if I can't, at the end of the day it's not actively affecting my ability to use the console. Though, I do like seeing how many hours I've logged in a game and would like to get it working again if possible.
