o.k - finally managed to see those immages, and that's really strange...

Because, when I open the app, it always displays all the instrutions in my language (German), but the Mnemonic in English. If I switch my mobile language, say - to spanish, it has all the instrutions in Spanish, but the Menemonic remains in English. But in your case, the instructions are in English, but the Mnemonic in Korean?

Thats weird, unless you changed the settings of your mobile form korean to englisch just for display...

I'can't test if the Mnemonic would be in a different language (other than English) it I would re-install the app with another system language (because the app can't be downloaded anymore), and if then, just typing the Menmonic in whatever language it is displayed would work... But as I figured out, the tool definitely doesn't work after you selected a language (every language). So, if not selecting korean as language, but actually just typing in your Mnemonic would help - I dunno.
