Rasandrik Sorry, but I'm not sure what you are suggesting here.
Localization for LE Tools will incorporate game translations and also have its own translations for stuff that's related to the site UI. I mean I can't fix game translations and I can't ask people who work on translations for LE Tools (purely voluntarily) to translate thousands of game texts...
I know there are issues with translation in the game, but I can fix probably only item property formatting to an extent and that's about it.
You can always report bugs in game translations to LE devs, eventually game translations would improve. And since LE Tools uses game translations, you'll see them in LE Tools as well.
