Uhhhhhhh bad, really bad... I think it was too hot yesterday... fixed now. Thank you very much for your hint.

Thanks for fixing.

Thanks for fixing! I see there are a few other pages starting with "Busefilter". Should they be removed?

These are remains in case the move/fix was not possible because new translations are existing. They can stay, we do never delete old translations.
