Hi CJ Freeman,
We've recently made a design change, where the green plus button beside the customer field has been changed to a grey plus button. This isn't the problem, however an issue occurs when a customer is selected in the customer field, the grey plus button changes to a grey pencil icon button. So our customers who were use to clicking the button beside the field thinking that they were clicking the plus button and adding a new customer, are actually ending up editing existing customers.
Please click on the link below to view a video demonstration on this:

To ensure you get the plus button to appear, what you need to do is scroll to the top of the drop down list in the customer field and select the empty white space cell. This will then cause the grey plus button to appear and ensure you are adding a new customer, as oppose to editing an existing one by mistake.
Therefore, the new customer's account will contain one or more invoice which relates to the new customer and rest of the invoices that relate to the customer which has been replaced/ overwritten. You'll need to edit the new customer to the old one, then add this new customer and edit the new invoices so that they are allocated to the new customer.
I'm extremely sorry about this issue, as I understand it can be quite confusing.
Please feel free to contact us if you need any further assistance.
Regards,
Shaz
