Article translating confusion!!!!!

[I.m.Geniza]

In the German immersion translator, there is an article that is written in 100% English. Should the article just be copied or should it have been placed in English to German translating? I can translate to German but the article was put in the German to English. (if the english article is in the german to english translator what do I translate?
Here is the article:
