List Styling: Images spilling over into next list item

I’m currently experiencing a problem with this plugin on a blog for the website I run. We use List Category Posts to generate a list of blog entries. Our posts are usually visual with a few images. In some of the list entries, the images from the post spill over into the next list item’s area. You can see the issue here. If you scroll, you’ll notice this in the 4th and 6th entry down the page. Any way I can remedy this?
