Discount not getting applied

Issue is that the "discount" field in the "create invoice" section does not actually take the discount off. For this, you will have to create a user in WordPress, and then create an invoice in M2 and set it to "billed"... then log into the site with that new user to complete the payment for the paid membership. When you get to the "checkout" area, it still displays the set amount of the invoice, not with the discount applied. Please check the chat transcript for more info.
