[Resuelto] I don't see the Dutch flag in the HTML for the dropdown

- I've translated this page to English and Dutch: enlace oculto
- The languages enabled for my site include English and Dutch on enlace oculto
- I have Custom language switchers enabled

But when I'm on page enlace oculto and inspect the HTML of the language picker dropdown in the top left, I don't see the Dutch flag in the HTML for the dropdown.
