Thanks for updating the translations! There are still a few missing:

WARN[0000] missing translation                           lang=sv translation_key=alert-insecure-environment

WARN[0000] missing translation                           lang=sv translation_key=tooltip-burn-secret

Regarding the Spanish translations: Feel free to add yourself to the translators list for Spanish and add those translations! There are also several seven translations missing; it would be great to have that complete again.
