Carousel shows blank image

All of my posts have images, but for some reason, with the carousel that is built into this theme, between my first and last post in the carousel, there is a blank space that just shows the background of my site.

I have looked for other suggestions but I haven’t found anything that helps- such as deleting white space in html, looking for extra <p> tags and removing them.

The page I need help with: [log in to see the link]
