I have just noticed if you apply a payment and select to add it to express accounts all is well but if you click on open invoices it still shows the payment is outstanding for that customer. It also allows it to receive another payment. Once the payment is made should't it show 0.00 not what the invoice was.
If you select one of those customers from the customer list it shows they have a balance of $0.00 which is correct
This appears to be a very major bug, what can Ido to fix it or is it a programming issue
