Appian Translation (german)

Hi Community,

we are using currently Appian 21.3 on premise. The system language is German.

The translation went down hill during the last versions from funny and incomplete to really "cant ignore it any more and makes my daily life difficult".

It is just insane and awful.

Incomplete translations - error messages still only translated partly and the result is a mixture of german and english,

inconsistent translations - different translations for the same words within the same window

just so completely wrong translations, that I was confused once or twice for some seconds how to proceed. - like translating the verb "load" not in the sense of "to load" and more like the noun "a truck load"

Do you guys have any idea how to place that as topic at appian? Support case(s)? 

Kind regards,
Richard
