Individual Blog Post Page not looking correct

Hi All, I’ve got 2 websites and I want things to be identical for the most part. I’ve checked settings and custom css and can’t figure this out. My main ‘blog’ page showing the list of posts look alright but on one site the individual post looks messed up. The first link below shows that below the menu there is some strange banner with the title across it. The second link shows how I want to look. Any ideas what I’ve got set wrong to make this look like the NJK site?

Thanks!
Noah
