What this means
You already have a product on this GTIN. One GTIN identifies one product. That is the whole of what a GTIN is for.
Why it usually happens
A second import of the same row, or a variant that should be a batch of an existing product rather than a product of its own.
What to do
Open the product that already holds the GTIN and edit it. If the two really are different products, the new one needs a GTIN of its own.
