Slideshow not playing automatically

Hello, I was wondering if anyone could he me with a small issues that i’m having.

The issue is that I have two slideshow blocks on my homepage for my website, and I have them set to autoplay with a 5 minute interval. Despite this though, the images do not move. I have changed themes and the issue still persists. However, when in edit mode the images do move.

Can anyone tell me why this is the case?
