Why are my variant rows not importing when the parent product title is only on the first row?

Some supplier feeds use a hierarchical CSV format where only the first row contains the full product title and metadata, while the following rows contain the variant details but leave the product title blank. Shopify requires every variant row to include a valid product title. If variant rows have an empty title, Stock Sync cannot group or create variants, and the import will fail. To resolve this, ensure the parent product information—especially the title—is filled down into every variant row before syncing.
