[Решено] Translate the

Background of the issue:
On the page скрытая ссылка the button with 'Laad meer' has to be translated into 'Load more'. The text is translated with WPML, so I don't know what is going wrong here.

Symptoms:
The 'Load more' button is not translated and is showing 'Laad meer'. Additionally, it is loading Dutch articles instead of English ones.

Questions:
Why is the 'Load more' button not translating correctly?
Why are Dutch articles loading instead of English ones?
