Top Buttons disappear on category pages?

Quick question: I have added a few custom buttons on the top row (next to the Latest button). They appear fine on the Latest page, but vanish when I click on a category page (and thus only see the Latest button).

How can I have them appear on the category pages too?


How did you add the buttons, can you clarify? Maybe @Johani can advise, if you provide a bit more info.
