On invoice let customer make payment. how do i get rid of green dot in box as invoice now being paid by D./D

Hello Oliver6, 

Welcome to the Community page, 

Do you have paypal or go-cardless or anything attached? If you dont and you have the payment details on the invoice then can you turn it off in the review and pay section in the main cog wheel>account and settings>advanced >email options and change it to plain text that should resolve your problem. 

If you have any Q's please feel free to reach back out to us again.
