When a delinquent account is finally paid, the creditor must update the current status to paid (i.e., no longer delinquent after that date), and the current balance to $0.
Prior derogs remain under payment history profile, and the payment status is updated to show the level of delinquency at time the debt was paid.
I see nothing improper except possibly the under-reporting of payment history derogs by EQ and TU.
A dispute is likely to result in addition of reported prior payment history profile derogs rather than the favorable update or removal of any derogs.
I would not advise pursuing a dispute........
