Usually Customers have some specific translation requirements to the terms. In that cases jobs come with Glossaries.
Some terms appear in a darker yellow that turns into grey, when hovering over it, with a warning message: "Glossary: only edit if necessary".
This means that the term should remain as it is in the Glossary. However, it's important to ensure that its use is correct in terms of gender, number or other specifics of the target language.
