Hi there,
Welcome to SeaTheme forum.
Please use the inline style codes –spacing-grid:20px;(for desktop) and –spacing-grid-m:10px;(for mobile) to define the items spacing, add the codes into the parent module-inside node of the Grid.
HTML:
<div class="moudule ...>
<div class="moudule-inside" style="--spacing-grid: 20px; --spacing-grid-m: 10px;" >
<div class="container-masonry ux-ratio-43 ..."
You can find the Grid section on Doc: https://www.dropbox.com/s/yau1kx7fmeuko9i/QQ20220205-160216.jpg?dl=0
