Why this issue is happening
When multiple offers with the same value for the VIN [vin] attribute for a country and language are uploaded in your product feed, a duplicate offer is created. A duplicate offer may cause serving issues and impression loss in your Merchant Center account. For example, if offers 'us/en/123' and 'us/en/124' use the same value for the VIN [vin] attribute, this will result in a duplicate offer.
How to fix your issue
To fix this issue, make sure that only one offer exists for each VIN [vin] attribute within a specific language and country by modifying or deleting the duplicate offers.
Creating multiple offers for the same car (using the same VIN) that serve in different local shops may also cause duplicate offers. If this happens, remove the duplicate offers and use the vehicle fulfilment [vehicle_fulfillment] attribute to enter multiple shop codes for the same offer.
