if I understand your post correctly, you mean the shelf icons are different.
you can change to any of the preset shelves by selecting the tabs (3rd menu set down), most likely the tutorial has either the polygon shelf or the surfaces shelf active.
If you want to add an item to your own shelf select the custom tab and then whilst holding down Shift + Ctrl + Alt on your keyboard navigate to the item in the top menu set and click on it and it will appear on the currently activated shelf i.e custom

hope this helps regards J.S.
