portal/backend/src/main/resources/i18n/fr.json:1090

• New translation keys ("forms", "userbook", and the "userbook_*" keys) were added only to fr.json. Since portal also ships en.json and loads translations by Accept-Language, these keys should be added there too to avoid missing/undefined labels for EN users.
