Parallax effect not working

I have a Sydney themed site and am using the frontage template for a page with site builder elements. I have a couple of rows with a background image. Previously the row would have a nice parallax effect. Now the image just scrolls leaving the row gray on scroll.

Any suggestions?

Hello there,

Please add the css code below to the styles.css in your child theme if any, or use simple custom css plugin:

.panel-row-style {
    background-position: center center !important;

Let me know how it goes.
