There is no requirment that a derog be reported within any set period aftier its occurence. If the late(s) occured, then there would be no basis for a dispute of the reporting of the delinquencies.
However, the current status should not show as delinquenct, but rather as paid. That is a readily correctible error.
You can handle informally by placing a call to the creditor. if you wish to handle formally, then you can either file a direct dispute with the creditor, or send the dispute to the CRA and let them handle the processing. Handling informally will avoid a pending dispute appearing in your credit report, and thus temporarily impacting your score.
A furnisher always has the option of simply correcting any inaccuracy, so they will likely correct the status without any deletion.
If you wish the account or any derogs deleted, you would send a GW request to the creditor,.
