Hi, @kevinushey
Thank you for your waiting.
I updated latest version (Version 1.3.929) to my laptop and try to attempt same import operation previously.
Unfortunately, I faced same issue. We can see Japanese sheet name but when I select Japanese select name in "Sheet" select box then same error happens again.
So could you please tell me what is next step if you have any idea?
Thank you for your help.
Best regards.
Thank you.
