Microsoft Money 2003-Reports showing double amount

[addicted]

I am using Microsoft Money 2003 since long. I am recently facing one error which I think might occuring due to some settings problem

When I create Invoice for a Customer, I click on Enter and the Invoice went away to the list. After when I check the CUSTOMER BALANCE, the same Invoice automatically DOUBLE the AMOUNT, for Example I create an Invoice for 1 item priced at 100$, CUSTOMER BALANCE REPORTS shows the same as 200$



Please advise what can I do in this regards as maintaining customers balance is a big problem for me now



thanks and regards
