When including dynamic product grids in content, it's typically not desired to show the same product multiple times. Instead, maximizing exposure to a unique set of products is preferred.
Enable automatic deduplication
A Remove Duplicate Products option is available in the Details pane for the Container of your content. When enabled, duplicate products get removed automatically.
How removal works
When utilizing the product deduplication feature, products will only appear once within all dynamic grids used in the content. Additionally, if multiple products share a parent_product_id, only the first product will appear within the content.
For example, a template has a grid for cart abandoned products and a second grid for recommended products. If Product A qualifies for both grids, it would only appear in the cart abandonment grid, because that grid appears first in the template. If Product B shares the same parent_product_id as Product A, then Product B would also be suppressed, whether it appears in the cart abandonment grid or the recommended products grid.
