Chocolate and Steel review for Retail Barcode Labels

Hi there! Thank you so much for sharing information about this issue! When generating barcodes in the Retail Barcode Labels app you have several options to choose from; to create barcodes for all or specific products, to generate barcodes only for products without barcodes, or to replace existing barcodes with new ones. To avoid duplicates, we would advise making sure that you are definitely selecting the option to create barcodes only for products or variants that don't have barcodes yet. If you are already doing so and the issue persists it would definitely be worth reaching out to our Retail support team via https://shopify.link/vRn so we can see if we can establish the root cause of the issue and fully resolve this for you. Thanks so much! - Natasha, Shopify Support
