Slideshow showing not moving to next post after adding excerpts to posts

After adding excerpts to posts, the homepage slideshow is not moving or cycling on to the next post with its featured image within a few seconds. It stays as a static page. Also the excerpt language is displaying as part of the slideshow. We would like just the post name and image to display in the slideshow and be clickable to go to the post displayed at the time in the slideshow.
