Fibre names under Material certificates appear in your own language, matching the rest of the assessment. This covers the fibre list under each material, the per-fibre certificate rows beneath it, and standalone fibre entries where no material name was given.
The list is ordered alphabetically by the translated name, so a certificate is quick to locate.
Translation happens when the page is opened, so assessments submitted months ago display correctly straight away. Nothing needs to be resubmitted or re-reviewed, and existing decisions and comments stay as they are.
The material reference name a supplier types by hand stays exactly as typed, since it is their own reference rather than a fibre name. The supplier-facing form is unchanged.
