Credit bureau still showing balance after BK

[tradinglife]

Our chpt 7 was discharged October 2010, 4 different credit accounts are still showing up with balances, they are listed as charge off's with no mention of the bankruptcy. The other 10 or so accounts are showing 0 balance, with comments " included in bankruptcy. Is this normal, or should I try to have this corrected? If so, how do I go about correcting this? These are on trans union bureau, I have not looked at others.
