Full width not working

Hi there,

I posted in the page builder support forum and they directed me to the Astra support. My problem is that on my homepage, the “full width” option on page builder doesn’t work, as seen in the white row. I want my row background to stretch all the way to the screen but keep the content contained. I’ve selected “full width” on the Astra layout, and “full width” on the individual page layouts, as well as the page builder row layout. The support person said the following code is preventing the row backgrounds stretching to the edge of the screen:

.siteorigin-panels .siteorigin-panels-stretch {
max-width: 100%;
margin-left: auto !important;
margin-right: auto !important;
}

How can I fix this? Thank you!
