Thanks for writing in! The header in X theme is global which means that it will display in all site pages and posts. The display order would be the logo/menu and then the page title or landmark header. You cannot simply switch the order by display the blog title or Landmark header first and then the logo/menu of the page.
You can however add a slider and assign it above the mastheade or above the logo/menu in some page and you may also add a slider below the mastheade (logo/navigation) in some pages too. To know more about slider and how it can be applied in your site, you can check it here: https://theme.co/apex/forum/t/troubleshooting-revolution-slider/197
If this is not what you want, would you mind providing us screenshot or an example url where we can have a clear idea of what you really what to have in your header.
