Gallery Building Blocks do not show correct alignment??

[BDavis]

I'm using Word 2007, when I go to add a page number and look in the gallery
under "simple" number, of the three examples the first example and the third
example show the number on the right side of the page and the second example
has it in the center.

How do I correct the first example to show/insert it on the "Left" side of
the page????

Thanks
