I’m not allowed to comment yet, so I am going to try and answer your question with the small amount of info you have provided.
The area you show in the red box seems to be a post and not a page. You should make sure that your home page content is on an actual page and then delete the post.
Next double check you have set your page as the home page in the dash: Settings > Reading. Here you can select “Static Page” then choose which page to use as your home page from a drop down list.
If this doesn’t solve the problem we’ll need to see your theme code to help more.
