I marked an invoice as paid. I have changed this to unpaid but every time I send the invoice the client receives it with Paid wrote across it in green, please help

Hi julies1,

This may be caused by a cache issue with the invoice, please try following the steps below:

1- Open the unpaid invoice and go to more > copy on the toolbar

2- Click save & send the copied invoice (you can edit the email when sending to change to a personal address, to see if this is now showing correct before sending to the customer)

3- Delete the original invoice 

Let me know if this works!
