Uploading through Upload Wizard (e.g. https://commons.wikimedia.org/wiki/special:uploadWizard?campaign=wlm-at&fields%5B%5D=32171&fields%5B%5D=47.70159/15.79294&captionlang=de&caption=Sog.+Huthaus%2C+Glockenhaus+am+Knappenberg+%28BDA-HERIS-ID%3A+34175%29%2C+Kleinau+23%2C+Reichenau+an+der+Rax&descriptionlang=de&description=Sog.+Huthaus%2C+Glockenhaus+am+Knappenberg&categories=Huthaus%2C+Glockenhaus+am+Knappenberg%2C+Reichenau+an+der+Rax) asks for commons categories and offers an example (when language is set to de): 'z.B. Säugetiere im Etosha Nationalpark'
The category does not exist (it is 'Mammals of Etosha National Park'). Nor can I type 'Säugetiere im Etosha Nationalpark' and it gets automatically translated to the correct category name.
So my proposal is not to translate category names in the upload wizard, as this is misleading.
