Font bug when building batch solver in GUI of MFix-20.3.1

Recently I upgraded MFix in my laptop to version-20.3.1. And when I tried to build a batch solver in Windows, the outputs were shown like below:


If I copy the outputs to a .txt file, they can be displayed normally. So I guess there maybe some problems in the font part of GUI. I tried to find where it is but didn’t get anything. Is there anybody who has met with the same problem?

This problem is fixed in the latest MFiX release (21.3).
