Hi ghulst,
have you checked if your theme does support sub-menu items? Some WordPress themes don’t display sub-menu items, which could be the reason for your issue.
If the menu item itself doesn’t save, it could also be related to limitations on your server. In that case this could be helpful: How to Remove the Menu Items Limit for WordPress.

The menu supports sub-menu’s. I’ve done the htaccess vars edit and now it works. I guess that wasn’t really solved in 4.5 then. 😉
