One of the features that Microsoft implemented with Windows XP was the concept of personalized menus. This is where you click on an item that has drop down options and it only shows you your most commonly used items off the menu rather than the whole thing. Then in order to see the rest of the menu items you would need to click on the down arrow at the bottom of the menu. They also started implementing this feature into Microsoft Office as well.
If you don’t like having to click the double down arrows to see all the options in your menu items in your Office application there is a way to turn it off. Microsoft has this feature so only the most commonly used menu items appear to make it "easier" to find what you need. After changing these settings when you click on a menu item such as File, you will see all your choices.
To make the change go to the Tools menu and select Customize in any Office program. A Customize dialog box opens.
Click on the Options tab. Under the Personalized Menus and Toolbars section check the box that says Always show full menus. Click on Close.
