The fonts of the modeline don't render properly

[deepnetni]

I have set the font family of 'Input Mono' and use the all-the-icons modeline.

However, the fonts of some parts in the mode line don't render properly.

Obviously, the font in the box above is not the 'Input Mono' font.

To check the faces status, i run the list-faces-display command, and found that in addition to mode-line segment, the mode-line-inactive is also abnormal.

How can i solve this problem? Thank you very much!

I found that the theme i used is the root cause of this issue.
