Hey @cruzlx, thanks for the post... touching >100 files makes this much harder to review. We should keep these changes to the canonical English versions only, and also avoid touching config files like the package-lock. Please do me a favor and revert the non-English and package-lock changes, then I can get eyes on this. Thanks!
