after filing bankruptcy, law leave these accounts open with balances

Hello,
You must have had major problems in resolving credit reporting issues to help other people resolve theirs! My question is this: after filing bankruptcy and getting a copy of the credit report, I disputed the accounts that were included in the bankruptcy because the report stated there was still an account balance, past due amount and that the accounts were still open. I sent a copy of the bankruptcy along with the dispute forms and when I received the response from the credit bureau they had not changed anything.
Can they by law leave these accounts open with balances and past due amounts showing on the report?
Thank you so much for your help!

I think they have to show account included in bk and zip the balance due part. Most times bureaus have to be promted. Well I should say always have to be prompted. No prompt no action. bureaus are in the data business. But yes most all credit items will show negative for 7-10 years even with the bk. Bankrupcies resolve debt issues not credit issues. 2 different issues with the same subject.
