Edge Issues – WP, Divi, JavaScript and Microsoft Edge

This site is acting weird. When you first go to the site, it works fine, but if you navigate away from the home page, then return to home page, some elements fail to load or don’t work properly.

1. The main buttons (Request A Quote, Get Advice, Request Service) should bring up a pop-up form.
2. The Vehicle Services slider no longer displays the images, nor slides, though the buttons do work.
3. The “Read More” button displays the expanded text instead of hiding it.

A similar problem also occurs on the Video Gallery page. When you first visit the page, it works fine, but if you navigate away and then return to the page it fails to load the videos.

Additional Info
1. This problem seems to only occur on Microsoft Edge. Chrome and Firefox display everything correctly.
2. We have other sites using the same elements and they appear to work fine in Edge.
3. A simple page refresh usually restores functionality until you navigate away from the page and return again.

Wordpress: Version 4.9.8
Divi: Version: 3.0.98
