There are some rules on the default SellerDeck navigation bars to control which navigation button appears on which page.
If you want to remove these rules, and have all buttons on all pages, then just go to 'Design | Library | Layouts' and expand the 'Navigation Bars' group.
Double-click on the navigation bar layout you want to edit.
Remove every green 'block' tag you see there EXCEPT the ones around the 'Up A Level' navigation icon.
You will now have every navigation button appearing on all pages.
