Please help with a few problems

Hi, I’m using premium Enigma theme, (updated from the free Enigma theme version) and I have a few problems:
Site in mobile:
On Mobil, when clicking on the main menu bottom (hamburger) which is on top left, the home menu bottom is showing on the right but I can’t see how to navigate, and sub menu bottoms don’t appears.
Also the section under the slider becomes too thick, the navigation arrows are too far from the slider. The same is with the portfolio section. The navigation arrows too far underneath the portfolio image.

Menu:
In menu, the main link bottom of the submenus has a deferent color, and I’d like it to be same color like the rest of the menu. Also the shadow of the bottoms changed his color and menu lost its opacity. How can I change it?

Header:
In header, I would like to push the text next to the logo a bit down from where he is, but without making the header thicker. Is it possible?

Here is the link to my site https://benedek.gingerlime.com/
Help would be mostly appreciated. (Sorry about my English), Thank you.
