How to reset Retail Barcode Labels on a POS system integration?

[NationalworkQLD]

Good afternoon,

I added the Retail Barcode Label App to my Shopify website and clicked create barcodes, expecting it to create barcodes for those which did not have barcodes, however it seems to have created new barcodes for everything on the website including those which already had barcodes.

Is there a default point to which we can reset our Shopify website.

My issue is that we are trying to integrate a Retail Express POS system with Shopify, but none of the barcodes and SKUs match

Regards,
