Squares instead of Korean characters in SDL machine translation

Question

Hi, 
 I am using SDL Trados Studio 2021 and have a problem with machine translation which has appeared since Studio 2019. 
 When I translate English text into Korean, I usually use any of machine translation tools, such as Google Translate, Microsoft Translator, and SDL Language Cloud. 
 However, the problem occurs as shown below. I don't know why it is happening.

For your information, the source language is English, and the target is Korean. In the target column, weird squares appear instead of Korean characters. 
 I 'd appreciate if anyone could help me resolve the knotty problem. 
 Thanks.

 Looks like a font problem. Did you try setting a font for Korean? (File->Options)
