Question
We have an item that has come over to shopify twice with split variants. The SKU is T2195/COR.
Answer
It may be that this product was created with one size, and when you added the other sizes, a new product was created.
We show the product with three sizes, so if you delete both products and then let us know when they have been deleted, we can resend the product. It should then be recreated with all the sizes.
