See: jolla-settings-system | Dutch (Belgium) community | Sailfish OS Localisation.
It says 1 word in 1 string is untranslated, but if you click on the ‘1 word’ link (which leads to Translate | jolla-settings-system | Dutch (Belgium) community | Sailfish OS Localisation), it just says ‘No results’. No such problem exists with an official translation, e.g. jolla-settings-system | Dutch | Sailfish OS Localisation.
Could this have something to do with the fact that the community translations will always show up as only 99% translated, even when 100% of the available strings are indeed 100% translated?
