battlelog not counting c4 kills or grenade kills

[glords]

I have had a lot of grenade kills and C4 kills and they never up date. I tried to log out then back in and still says 24 C4 kills and 100 grenade kills. I know that I have a lot more then that I was just wondering when they would be fixed thank you .And also on xbox 360 were still have freezes on the 2 levels that I said before.
