Why this issue is happening
Two or more of the products in your product data use the same item group ID [item_group_id], but don’t include multiple values for any associated variant attributes, such as size [size] or color [color]. This could result in showing duplicates of the same offer, rather than showing 2 different offers that vary by size, color, or some other distinguishing attribute.
How to fix your issue
To make sure we can correctly identify products that use the same item group ID [item_group_id], submit unique values for associated variant attributes, or remove duplicate offers from your product data. You can also resolve this issue by removing the item group ID attribute.
