Yes, thank you for reporting this! This is a known bug we already have logged in our bug tracker.
I do not know a timeframe on when it might be fixed, but we are aware of it and we will work on it.
You can type in Korean if you want. We do not currently have a Korean manager but we can always use Google translate to read it and we do have some Korean team members we can ask to translate for us if needed.
We will likely reply in English though for now, if and when we do reply. We apologize for not being able to reply in Korean
