Product gallery image on mouseover

I am having pretty much the same problem as the person in the following thread.

https://wordpress.org/support/topic/2-2-4-product-gallery-images-on-home-page/

However I can’t seem find a solution to fix the issue.

My URL: http://www.laxstreetwear.com/US

I am not sure what version of shopisle I am using however wordpress is telling me that I am using the latest one (I actually just updated it 2 hours ago).
Also, I am not sure if this is relevant but I am using a child-theme.
Please help as this is driving me crazy!

Thank you
