Some bugs of description texts and localization

At the “Car Tirm”->“Driver Aids & Safety”->“Optimaize Weight” and “Weight Distribution”,these description text in game are just copy the same things from “Cam Profile”,but I think it’s a bug and can be corrected easily.
By the way,where can I change the translation texts(localized texts)?,some meanings in Chinese text should be corrected,like “Lighter” in weight has been translated in meaning “more bright”,we know it should be upgrated,right?
