No matter what I do, i cna't get our hamburger menu to use the menu i created called "mobile-menu" -- i try selecting it in appearance - logos - vertical menu , but it just doesn't seem to want to change 9and also I don;t see a "save" button there). How can i get the correct menu to show up?

Nevermind, i found it, but there are so many different places to change this and only one that works!
