Psoft 9.1 Adjust Paid Expenses

i am trying to perform and adjust paid expense process in Psoft 9.1 and when i journal generate the entry i get 4 lines.  two lines are correct adjusting from old expense account to the new expense account however i get one with zero dollars trying to post to the liability and the other is for zero dollars adjusting a blank account and department.  is there setup i am missing or am i performing the adjustment incorrectly?
