Dropdown menu distorted and Unwanted space on right side on mobile viewport

Hello guys, I’m new to webflow community and currently working on a friend’s project. I’m having some problems, firstly the dropdown menu isn’t showing up properly. It shows up halfway on the home section maybe because of all the margins I use. What would be the best solution for it? Also, I have white space on the right side when I switch to mobile viewport, I set the overflow to hidden still showing up.
Here’s a link to the project:
