before and after slider by Aaron Bolton

Hi there, I’m having some trouble with the Before and After slider plug-in not being visible on page preview. Its showing up fine in the Divi back and front end, but when viewing live view, its not visible, yet the inspect source shows its there. I’ve disabled lazy load on Siteground, I have latest Divi and wordpress and php 7.1 . (as at 18/02/20). I’ve taken some screen shots if this helps, but can’t see how to load them to this forum? Hoping its an easy fix?
