Hello, @Hostelion Digital,
It is there in our theme language file, actually, that word is with spaces in the code and file as well: “Proceed to checkout
“ so you should have look at these spaces.
First of all please click on the SYNC button and after completing the synchronization, please click on the save changes button and then find and translate the word as per your requirements.

If you still face the issue then please share your site WP Admin URL and Credentials with me in a private content area of this topic so that I’ll check and solve it for you.
