That is the way it is supposed to be. Just ignore the German part as it is a translation of the English part. In other words, the page is duplicated, top half in English and exactly the same thing on the lower half translated into German.
The only downside of this is that a German-speaking member may post some really valuable info in the German section, which will be missed by the non-German speaking members.
I just use Google translate to get the gist of what is being said though.
