A Slide Keeps Showing on the Front Page

One of my subdomains, http://stories.thirdscribe.com has Slide-In enabled. I've made three slides so far, and all are specific to a particular post.

However, one of the slides keeps showing on the front page of the site. I do not want that to happen, the sliders are specifically for posts.

Why is this happening, and how can I stop it?
