Search results in the slider

Hello, I am working in a SP2013 on-prem environment.  I have set up a Content Search Web Part using the slideshow control to display the results and have limited the results to 6.  The issue I am running into is that if my search only returns 3 items, then the last 3 items just show a blank space.  I would prefer for it to go back to the first item instead of going blank for items 4, 5, and 6.  I have looked around for how to do this but couldn't find anything so if you could give me some help it would be much appreciated!

Thank you!
