Facebook "og:description" not working even though its displayed

Hello, I am having troubles with facebook posts lately. It worked all reight before, just today it started not working.

When entering my article to:
https://developers.facebook.com/tools/debug/

concerned news article:
http://www.asylantenvergewaltigung.de/oesterreich-gruppenvergewaltigung-serienvergewaltiger-mord-und-onanie-durch-asylanten-stark-zunehmend/

You can see that there is a og:description tag, still the description does not show in the post.

What can I do?
