Good afternoon people. First time on here so please be patient with me. I have a major issue since the latest update. I have customers who changing site addresses but now when I change a site address on a quote or invoice it saves the site address on ALL previous quotes or invoices as well. This has affected 2 years worth of invoices, I have back ups but when I load them it changes the site address to the latest address. It happens to each account separately. Does anyone know why and what I do about it
