Yeah, some of them (like the ones before "that" and "when") are a negative transfer from German. Trivial to fix though, and something tells me they will. Definitely a beautifully put-together page.
A "negative transfer" is when you apply habits from one language to another and make usage choices that are not necessarily errors, but sound awkward to native speakers. It's not so much a translation thing as it is a non-native speaker thing.
