Every page displays the sub-header as default. The sub header contains two elements; the page title and the breadcrumb menu. You can disable these elements globally via Customize > Styling Options > Sub Header or use the Design Options for a single page/post.
You can disable those elements by using the “Design Options > Sub Header” inside the page/post edit screens to overwrite the global settings individually. When you hide the both elements the sub header will not be displayed like the home page examples http://businesslounge-demo.rtthemes.com/home-page/
