Banner in 7.1 has no animations between slides

Site URL: https://www.alliancepackaging.ie/

Hi

I have two large gallery slideshow banners (full width) at the top of my homepage but the animations between the images are not working. When I apply one it animates once and then never again. I have some code on the site but this issue was there before I added it. I wanted to see if anyone had come across this before. Site is in 7.1
