Slideshow not working on Desktop

[PodCloset]

I am using a free shopify theme. I have added a slideshow to the theme but it is only working on the mobile version and is a blank space on the desktop version. Can anybody help or explain why this may be happening? 

Thanks!!

background-color: transparent !important;
}
