All items in my navigation menu display properly except for Folders. I have tried to place folders in both the Primary and Secondary navigation menus and neither of them display the folder with the drop down menu like it should. This used to work on the site before but now has suddenly stopped working. When I add the folder to the Navigation menu, all the other items in the menu displace to accommodate the new folder, however there is no button for the folder in the menu. This bug happens on both mobile and desktop.
