When I create a new invoice (+, New Invoice), a form appears in which the text box under Customer Payment Option is pre-filled with text. When the text is deleted the text box prompt reads “Tell your customers how you want to get paid”.

I want this text box to be blank every time I generate a new invoice. I wrote text in this box once, and now every time I generate a new invoice it is pre-filled. How can I permanently delete this text? There does not seem to be any options for this in the Manage bar or within the Design Template portal. 

Thank you.
