Automatically changed font while changing between languages (Korean-English)

Hello.

I am using Scrivener in macOS (Sonoma).

The languages I mainly use are English and Korean. In this regard, the chronic problem of my scrivener is that the Englsih font is not applied anymore while I changed language from Korean to English.

For instance, I was typing in English with Helvetica and changed language into Korean with Apple SD Gothic, and then when I came back to English the font was set with still Apple SD Gothic. I believe that the English font was supposed to be Helvetica. Thus, I had to set Font every time I change the language.

Can I get any help with regard to this font issue?
