Fnb closed&paid up account showing as Open and outstanding Balance on Credit Report

I settled my FNB loan by discounted settlement in August 2019 and received a paid up letter for the account in question. Checked my credit report to find that this same paid up account now reflects under closed account with an outstanding balance. I emailed their attorneys through whom i did the settlement payment etc.and they advised that FNB updated the profile as now on my report it shows under Open accounts when this is not a true reflection and that because of the settlement amount FNB lists it as a shortfall No i disagree and dispute this dishonest reflection from FNB regarding this paid up account.

Consumers run into financial issues but when they willing to pay for their faults by settling these accounts so why would a closed account refelect as open with an outstanding amount ? Please advise as I would like this account removed completely as per paid up letter, proof of payment i have with me and confirmed emails from the attorneys you use .....
