Posts displayed in two different ways on Cream Blog theme

my website shows blog posts in two different ways at once with the Cream Blog theme. I only want one way for the posts to be displayed – as below, with the samller images on the left. I want to know how to disable the other way – as aobe with the text in the larger images. This problem only occurs when I add a featured image to a blog post. I want to use featured images.

I would appreciate any help.
