Mission Plnner quick broken

I am using mission planner 1.3.63 ver.
I want to upgrade the mission planner to the latest version 1.3.77 ver. However, the letter of quick is broken as shown in the picture below.
1.3.75 ver has the same problem.
I don’t remember exactly because it was a long time ago, but I tried 1.3.66 to 1.3.69 ver to solve the same problem, but it was the same.
Please help me. Thank you.

what language is your OS configured for?

It’s in Korean. And the mission planner UI is in English, which is the default.
