when you export you will have two infos in your po:
# active language: English, id:0
# translation language: German, id:1
Visionaire will write the translations to the language with the id 1.
#: context:Kulisse0: Objekt0: '' angewandt
msgid is containing the untranslated text and msgstr the translated. You should check if this is matching. Also the comments need to be there because they contain the ids. If you still have problems send me the po and I'll check it.
