Page Title shows as Blog Post on Blog Page

Hello, I just decided to use Catch Box for my blog. I began to create pages and published some testposts. Strangely the title of the last page which is part of the top menu is shown on the blog stream directly beneath the featured slider in the style of a blog post. When I put the page into the paperbasket another page title simple appears on the same spot instead. How can I fix that? Only Blog post are supposed to appear on the Blog page. Thanks for help. Jessil
