Hi, Wegmanarts! BK is a derogatory, so I don't think you can change that. Just make sure that none of them are keyed as delinquent.
There just can't be any lates or chargeoffs after the filing date. The status itself has to be IIB the month after the discharge date with IIB and no balance and current every month after the discharge date.
The above thread shows there can't be any lates or chargeoffs after the filing date but I'm not so sure the three CRA's follow that to the T. You have to bug them.
You can try submitting disputes and ask for the wording to be removed.. They are not allowed to report any negative information after the BK file date. IIB tradelines are negative though.. When I was working on my reports and getting my IIB accounts removed, I saw a score bump every time. I think your time would be better spent adding positive reporting TL's and making sure no new negatives report.
