In a custom template file I'm inserting one of my custom menus:
<?php wp_nav_menu( array('menu' => 'Internal' ));?>
However the menu fails to generate the class current-menu-item for the current li item.
I am inserting a menu in the same way for menus in other pages without any issues.
What might cause Wordpress to fail output of the current-menu-item?
