Thank you for your reply.
As you suggested, I modified the CSV so that there is only one Original column and changed the other one to jp. However, even after switching the Language setting to English, the Japanese text is still displayed in the game.

Also, regarding my previous question: how should I translate character names in the Name column? What is the correct way to write them in the CSV for English?
Additionally, for menu items such as “Character” and “Current Location”, is it correct that I need to modify the related plugins and wrap the text like this in order to support language switching?
this.drawText(Hendrix_Localization("TEXT_HERE"));
Thank you very much for your help.
