Translation Issue with cart page in Dawn theme

[TeamMyFontinet]

Hello, we have translated our website from Dutch to French (myfontinet.com) by using the Translate & Adapt app by Shopify. We are using the Dawn theme. Every translation works correctly so far. But, when you add something to your cart in the french version and you proceed to click on 'buy now/checkout' to start the payment process, you are moved to a login page. This is correct behaviour, because we enforced it to make sure users make an account by using an email code. But the issue here is that this login page is always in Dutch when they take this route. If they just click on the profile icon while in French, they will be redirected to the french login page. So I started looking to translate the 'cart template' page to fix this issue, but it won't load as you can see here:

The check-out button that is redirecting to the wrong login page language is this one:

Does anyone know a solution for this? I've also tried a different browser since I thought it was a loading issue.
Thanks in advance!

I made sure that I translated all messages. I know that, because when I try to make an account by clikcing on the profile icon, it brings up the correct translated French version of the login page:

Looking at your reply, it's not clear what part of the theme code I have to edit in order to change the behaviour of the checkout button (the buttons that is redirecting to the store's default language). Can you be more specific?

I have found out this is a non-issue. This particular button will always redirect users to their browser's language, not the language that is selected on the store. So when I changed my browser language to french, this button would always redirect me to the French login page. Even when I selected Dutch in the shop store. So it works like it should, it just was unclear and I never thought about changing browser language earlier.
