The problem is that the menu icon is set with an absolute position. That means it shows in the top left corner, always, and doesn't 'move' other elements around it. You're going to have to add some margin to the SCLogin button to manually adjust it away from the menu item. Something as simple as the below CSS looks to work in the mobile view:
.sclogin-modal-links {
margin-left: 50px;
}I haven't tested what that does in the desktop view, and you may need to add some additional media query styles to make that margin only apply in the mobile view. Hopefully, that helps you understand the issue more and get you going.
If you need anything else, just let us know!
