Blog page is showing product lists.

Today I started with MarketPress using the GridMarket child theme. I added a page called "Blog" and set the template to "blog news" and published. I added it to the Top Nav and set the Theme Options post page to Blog. For a whole, when you selected the blog option fromt he top menu it went to the sample blog posts I amde. Now it goes to the Products page. Any help greatly appreciated! cultclassicposters.com
