Adding Pages the Product Theme

Hi Everyone,

I am very new at this, so my issue is probably very simple to solve!

I am using the "Product" Theme. I have installed the buddypress plugin. The pages associated with this pugin (activity, members, groups, forum) are working correctly, and visible on the second navigation tab as expected.

My issue is that no pages are appearing on the first navigation tab (on the Product Demo, these are the Welcome, About, Gallery, Blogs Pages). How do I add pages to this navigation area?

What drives the location of pages on the first and second navigation tab?
