Related label translation

It might indeed be a string that hasn’t been translated yet, or that was translated very recently and the translation hasn’t been released yet.

If that’s the former, you can follow this guide to contribute to the translation effort:
https://jetpack.me/support/getting-started-with-jetpack/how-can-i-install-jetpack-in-my-language/

If that’s the latter, the translation will be included in the next Jetpack release.

I hope this helps.
