Revolution slider not showing all slides

I am sure I am missing something small but a little help would be appreciated. I created a slider using one of the sliders that came with the Highend theme as a template. It started with 2 slides and I have added 2 more. The slider currently only shows 3 of the slides and will not show the final slide. If I reorder the slides and move the slide that starts the loop over again then it will show all four. How do I change which slide is the end slide so that all of my slides are seen in the correct order?
