Language button shows languages for which no translation is available.

I have changed it (on this page: https://developers.google.com/web/fundamentals/getting-started/primers/service-workers ) to a few languages but the english text is not changing.

Apologies for that. When a translation isn't available for a particular language it falls back to English. Clearly we need to do something about how that button works, but I can't give you a timeline.

Thank you for bringing it to our attention.
