Problems in minamaze child theme with Responsive Menu

Hi

I created a child theme of minamaze because i wanted to add a big logo on top of the menu.
I managed to do this but i have some issues with the responsive menu.

When i click on it, it opens and closes, but only once. After i did this manipulation, when i click on the responsive menu nothing happen.
It doesn’t opened or anything.

Please ca some one help me to solve this problem?

thanks
