If you're using the tabbed nav template, the pages will always show as tabs at the top, even if you choose a 2-column layout & use the bottom box to span a box across the whole page.
If you want the pages to show up as buttons on the side, you'll need to switch the guide to the side nav template, which only allows 2 columns (one with the page nav and then a larger one for content), unless you create a custom template to tell it to do otherwise.
You can change the template of a guide by clicking the image icon in the top right menu options on the page and then selecting Guide Navigation Layout. (It might be Guide Page Layout - it's the first option.)
Ah, your system is set to force everyone to use one template vs. being able to choose a template, then. Easily changed!
Go to Admin > Look & Feel > Guide Pages Layout and look at the first section on the page.
Change the selection to "Allow user to choose template" (or similar language) and click Save.
That will allow you to choose either tabbed nav or side nav when creating a guide and allow you to change the template while editing a guide.
