Windows Live Writer duplicating images

Hello, I am very new to blogging so forgive me if this is a simple question. I use the Ideation and Intent theme. I recently tried using MS Live Writer and posted my last two posts using it. I noticed that on the home page of my blog, it is showing the thumbnail of each image twice for the my most recent two posts (which were the ones I wrote/posted using LiveWriter.) If you pull up the actual post, each image only appears once. The images from these two posts also appear twice in my media library.

Why is this happening, and is there something I can do to stop it?
