What happened...?

I have not used this app for a long time, I admit it. But looking for something delicious to eat, I looked into this app. All recipes are now an English-German jibber jabber, which is hard to understand (and does not make sense). I could not find out whether I need to change any settings (are there any?) or whether the app has been poorly (and thats an euphemism) translated.
