Remove two navigation items on Mobile ONLY

https://www.berryorganized.com, I want to remove the navigation items, tools I use and admin skills on the mobile version as the anchor links don't seem to be working since the desktop & mobile sections differ, any idea on code?

Add to Design > Custom CSS

/* Hide items on mobile */
@media screen and (max-width:991px) {
.header-menu-nav-folder[data-folder="root"]>div>div:nth-child(4), .header-menu-nav-folder[data-folder="root"]>div>div:nth-child(3) {
    display: none;
}
}
