Some menu items not in hamburger menu squarespace mobile view

Half of my menu items are not going into the hamburger icon on mobile view. It's messing with the cart as well, making it so that site visitors aren't always able to access their cart. Menu works normal on desktop view.

I have some code targeting the menu but when I delete it the issue with the mobile view still persists.

. 

Can you share your website URL?

Thanks for the reply. I actually resolved this issue by adding this line of code:

/*Mobile Menu Navigation Fix */
@media (max-width: 850px) {
  .header-nav-item {display: none} }

Nice one!
