Korean font is broken

[Ram L]

Hello!

I'm using Adobe Captivate 2019 in English version with Mac OS.

I'm working on software simulation project now and I realized all Korean font is not working properly.

It seems like putting space automatically next to every single character as below. It happens to every buttons or text boxes that work with character.

However, it works good when I write text in other documents and then paste them to Adobe Captivate like as below. Below is exactly same text with above one.

Is there anyone who knows how to fix it? 

Thank you so much!
