Hi,
Thanks for your screenshots.
“Gallery on left/Right” are 2 special layouts. Please select the layout as “No template”

You could use the BM Content Builder editor with this template. All single portfolio(hero, slider, images grid, text block, etc) are created by the BM Content Builder. The Grid or Masonry Grid can built gallery section.


If you still want to use gallery section. Please select “Gallery on Right” template. paste the custom CSS code to “Appearance > Customize: Additional CSS”, it makes “Gallery on Right” centered.
.single-col2-text-wrap,
.single-col2-gallery-wrap {
width: 100%!important;
}
@media (min-width: 992px) {
.sticky_column {
position: relative;
}
}
Regards!
