ONIX Boutique Bern review for Retail Barcode Labels

For a long time all went fine with our barcodes. now suddenly it makes duplicates of barcodes for diffrent products, even the products have diffrent SKUs!! even we have only about 4000 diffrent variants-barcodes.... It is a huge mess for us, as we are traped in this App. All our products are in store POS an are labeld with barcode labels!! i hope to get an answer from the developers to help me solve this problem! Please contact us! It's a worst case scenario!
