Hi there,
You used the Visual Composer Hover Box functionality. As we are not the developers of that Page Builder and we only include the builder in our extensions list and because we do not have enough knowledge of the ins and outs of the Visual Composer code our options to help you here is limited.
You always are welcomed to use the Cornerstone which is the official page builder of our theme and you can use the Classic Card element to have a somewhat similar effect like the hover box.
But one thing that I see is that our latest supported version of the Visual Composer is 5.4.3 and you are using another version. Kindly backup your website completely, then deactivate and delete the Visual Composer. After that go to X > Overview menu and scroll down to see the Visual Composer in the listing. Install it from there.
See if the newer version fixed the issue. If not kindly get back to us again and we will provide a report which will ask our development team to report to the Visual Composer developers.
Thank you.
