Paypal saying unpaid invoice after payment has completed

[Thian]

Hi All,

 

With upgrade 5.0.2 I have a slight issue, after a order is placed, and the client pays for it via paypal, the client is sent out a Order Confirmation that says it is unpaid, shortly after if the client returns to there portal, it will say paid in Domain Names, and a second email is sent to the client called "Invoice Payment Confirmation", this states it is paid.....

 

The unpaid invoice is shown as soon as it is paid for, so this looks quite unprofessional, does anyone no what I can do to rectify this?

 

Thanks in advance
