2nd level submenu items not showing up in drop down menu

Bootstrap multilevel child menu should have :arrow_forward: to the right of the BREAST menu item under Procedures drop down Menu, but it is missing. Am I missing something?

Bootstrap 3 removed support for dropdown submenus.

Gotcha, thank you Foxaii.
