@Myself it happens. For my last name "王” when I got my Canadian passport it got translated to "wa**" in English but my driver license translate it to "Wong" I'm not sure why you don't understand sometimes there is multiple ways to translate a name like namjoon can also be spelled Namjun when they translate the name to English. I know multiple people both have the same Korean name but on passport one spelled namjoon one spelled namjun.
