Unfortunately, for now, there are no option to add the title, to the Blog Posts. (Maybe we can implement it in the some of next theme updates)
But until then you can do that in another way…
To insert a title above the Blog post, your Frontpage needs to be a Static,
So to make it a static,follow the next guide, from our knowledge base.
Once when you created the Static FrontPage, enable the slider on it, following next guide.
go to Customizing->Front Page Boxes->General menu, and set the Front Page Boxes Visibility to the “Front Page”
Add your blog posts and title above it using a WP_Bakery page builder plugin, following next video guide.
