Sales Invoice/Order Imbalance

Hi all,

I have a situation where it appears a credit of $7 was applied to a sales order before it was converted to an invoice, was then subsequently deleted and now MYOB appears to have fixed the Balance due to the amount including the $7 credit. See attached screenshot where invoice value of $190,060.56 less payment of $185,213.00 shows a balance of $4,840.56 instead of the correct balance of $4,847.56.

As it's a converted sales order, I can't delete any of the entries. And if I reverse the sale and apply it to the balance, I'll end up with a credit for $185,220 instead of the actual payment of $185,213.

Any ideas how to fox this issue?
