That's because you apparently modified the Default menus?
You can reset them back to the original ... then, easily build your own custom menus (no code reqd) following the approach here: (I've built 100's of such menus, toolbars and right click menus)
Everything you need is here ... see this link:
http://www.jamiessoftware.tk/articles/menubars.html Not sure it that article mentions it, but ... when you are in the Customize mode (dialog) ... if you hold down the Control key, you can drop and drag (ie, copy) menu items from one place to another ... handy for making a new menu that is similar another one.
