Problem with images showing up in Theme

I have installed the BuddyPress Daily Theme on my news blog, It has been working great, except for some reason, the theme is not showing the preview on the one of the posts. I thought it was because of embedded graphics, but two similar posts show it just fine on the preview.

Here is the post that is not showing up on the main page in the preview graphic.

Yet, this post has essentially the same content (embedded graphic) and it shows up just fine in the preview box on the front page.
