Replacing tinynav

Hi, I have only three items in my menu and I would like to use it like this in mobile views instead of tinynav. I've therefore deleted the Responsive Menu section from functions.php (catchbox-menu.min.js and catchbox-allmenu-min.js) so the tiny menu no longer appears in mobile views. However the original primary menu still doesn't show up, I just have the menu-header-container but no links. I've inspected the source code for the page in my browser and the correct html is there, it's just not being styled. I've looked in the viewport sections of style.css and I can't see anything that would prevent the links from being styled. Is there some other code elsewhere preventing the original menu styling from appearing on mobile?
