Hello @31n5ang and thank you for this. However, you need to delete the changes you made to the IT and KO languages. Just push the english source language fix, and our translation engine (Crowdin) will pick up the change and the translators for each language can will apply the fixes there. Making changes to the other languages outside of Crowdin causes problems. If you will delete those two language fixes, and leave the EN language fix, I'll merge your PR. Thank you again!

I'm converting your PR to a draft until those changes are made, just so it doesn't accidentally get merged. :-)
