Did you report it? If not, please do so next time you encounter the sentence, by clicking on the "Report a Problem" button that appears after you answer a question. Choose the "My answer should be accepted" option, and sooner or later it will be added as another correct translation. :)
well, 9 months passed but the mistake remains the same. It seems, that the button "report a problem" doesn't work at all :(
The button works perfectly fine. The problem is just that no one seems to have the time to work through those reports.
