Missing total amount on customers confirmation page

[nnscr]

Hello,

we've implemented a paypal checkout for a customer using the REST API. However, the paypal site does not show the total amount of the payment. What are the conditions that the amount is shown?

Also, can you get rid of the notice below the "continue" button on the bottom of the site? It says that one can check the content of the order before the actual payment, which is not the case in our checkout flow. Plus, can you change the label of that button? Our customer want's it to say "finish" instead of "continue"...

Thanks!
