As I can see, the first column from the footer is missing from the English page. Can you try to delete the fist widget from the Deutsch version of the page and create again the translation, please? As I can see, the translation for the other two columns is working very well.
What do you mean with deleting the first widget? I dont think that this is the solution of the problem. We had a similar problem with the translation of an english button. The problem is just the very right one that just disappears.
It seems that the first widget was set to be displayed only in Deutsch (using the selector from the end of the widget in Appearance → Widgets). Now I set it to be displayed in all the languages and everything is back to normal on English. Can you check this out, please?
