The App layout (Pop up screen) when the user want to create a Document the Drawloop question do appear standard always in the English language.
In multiple Language companies this is not wished and also this questions should be showed in their own language.
It would be fine this questions could be translated by Translation WorkBench from Salesforce like you can do with fields etc.

The answer from Nintex = The Visualforce page from the screenshot cannot be currently translated. A workaround is to create your own Visualforce page or to automate the button so that the Document package, Contact and Delivery option will be automatically selected and the user will only see the progress bar.

Example of a popup screen with English question.
