The naming of the files has to be:

fuel-<module>-<langcode>_OrgName/IndividualName.<FileFormat>

language/fr/terminology/desktop/fuel-desktop_translatewiki.net.po

Should be

language/fr/terminology/desktop/fuel-desktop-fr_translatewiki.net.po

This needs to be changed in FUEL.yaml in the translatewiki repo.
