★Why does the font name in the text style dialog show as blank?

Issue:

Why does the name appear as "blank" when opening the text style manager after switching the font style to a certain style?

Causes:

On the computer, there are two font files with the same name, ".shx" and ".ttf", and the software is unable to recognize which style to use.

Solution:

According to your needs, delete one of the font files and keep only one type of font with the same name on your computer.
