Studio Theme does not show blog posts :(

I've tried choosing the posts page in the Reading settings - I created a page called "Blog" and went into the reading settings and set up the posts page to "Blog"... but now, if I click on "Blogs" in the navigation I actually see the page like homepage.

Is there any way to show my posts on page called 'Blog' as I can see in the theme's demo?

Please, help me! I am totally stuck.
