I have installed the Material Teme UI plugin in my IDE, Intellij. This plugin does is apply a theme to the interface in an integral way (applying the changes in both the color of the syntax and in the windows and / or honeycombs of the editor.
The problem that I have is in the part where it shows me the structure of the program that I am doing (it is an aid that allows to see more graphically the methods, variables, etc. of your program), and that is that the icons, for example: methods and classes are not shown as they should

Can you solve it? How?
