I tested theTemplates 03template for German. Here is a screenshot of the template in German.
There is a small mistake in the first section of the template. The word Monat should be in the previous line, meaning:
Vorgesehene Themen für den nächsten Monat
In the last section of this template, there is an untranslated text. In Germany (however, I can't speak for Austria, Switzerland or more German speaking countries), it is unusual to add the state to the address (Bundesland).
