Well, I got this fixed on my own. So I wanted to come back and put what I learned in case this helps anyone else with the same issue. The Enfold theme has a performance settings tab with Enable Lazy Loading. And the site web host does caching (Flywheel/WP-Engine). So to fix the image animations, I discovered that the CSS was loading in a weird order causing the animations to fail. By turning off Lazy Loading and flushing the cache at the web host, it fixed everything.
Those instructions fixed the problem for me. I really don’t like editing parent theme code though. Thank you for the fix. I assume you will roll this into the next Enfold update.
Never mind… after clearing my Chrome browser cache, it resolved. Thanks!
