First of all you’re not using the landing page. Your home page is just showing the latest posts.
And that overlay can be hidden from the customizer settings >> Post information >> Header titles (in your case uncheck ‘Home page’). Although you need to update back to 0.9.2 to have that option.
Oh and normally on the home page in the overlay the site title and description would be displayed but you’ve left those empty. That’s why the overlay is empty as well.
