FNB credit card old outstanding amount reflecting on credit bureaus

I had an FNB credit card, Long story short I lost my job and the account was handed over to collection lawyers. My frustration now is I have an arrangement on this debt via lawyers/debt collectors but the old arrears amount is reflected on credit bureaus. I want to find out if the arrears amount can be removed and the outstanding balance reflected instead. I need assistance either from FNB or GL attorneys.
