bug in my theme Electro

Hi

I bought the theme electro a while ago.
Now I finally started and run into a problem with the categories.
Now I have looked at Madras, but there I read the same problem but not the solution.
I no longer have support, so I’m curious if someone can help me with this problem.
The problem I have is described as the first article on:

i hope someone can help me (sorry for my english)
