Different Unique IDs/SKUs but All Same Size

This error occurred because at least two of your variants for one product listing are the same size but have different SKUs/unique IDs.

Troubleshoot this issue: Make sure that each SKU or unique ID represents a different variant of the parent listing. One variant (i.e., one size) for the product should only have one unique ID or SKU.
