sorry if i'm driving anyone crazy

another question though, i have a nelnet loan on my acct. stating 90 days late and 120 days late. this loan has been paid off and reconsolidated with sallie mae. i've disputed and they've refused to remove the negatives. i vaguely remember reading something about if you paid off a student loan that negatives could be removed. did i read right? can someone enlighten me on this situation please.
thanks in advance!!
