Roland -if you haven't already you can go over to the German forums https://moodle.org/course/view.php?id=18 and mention it there. I looked at the translation too and agree with you - it is actually wrong.
(Edit - they already discussed it here: https://moodle.org/mod/forum/discuss.php?d=279906#p1204724 but haven't yet taken action on it. Might be worth a reminder.)
