In the admin assessment review, each row in the Packaging section shows an amber “Add missing translations” badge with a count when its component name is not yet translated into all your languages — matching what the Components section already does.
Clicking the badge opens the same translation editor used for components. Once every language is filled in and saved, the badge disappears without a page reload; filling in some languages lowers the count.
The languages checked are your enabled languages plus Chinese and Turkish, which suppliers can always answer in. This covers both order-level and per-product packaging.
Many existing packaging names are stored in a single language, so if you work in several languages you will see badges on most rows at first. They mark translations still to fill in, not an error.
