Moving Images with Scroll Animation


I am having issues with a template called Opale. The moving images on the right hand side of the ‘clients’ CMS page are not working. The animation is on the section called ‘sticky-section’ & the animation is called ‘vertical-movement’. Here is a read only link for the original template where you can see the images moving:

I have expanded on the template to create this site (read only link):

The animation seems to be all ok but it will not work in preview or when published.
I have renamed the page ‘experiences’.
The template has been great in general and I am very thankful for it. I would appreciate if the hive mind might be able to figure this one out.
Thank you very much.
