Why aren't duplicate variants being created in my Shopify store?
Why aren't the duplicate variants created for all my products using the Variant Dependent method in Custom Pricing?
Custom Pricing V1 does not support products where variant options are linked to metafields or metaobjects. If these are linked, variants may not get duplicated and pricing may not apply correctly.
In Shopify, you can recognize this when editing a product option (such as Color or Size) and Shopify shows that the option is connected to a metafield.
To resolve this issue, you can edit the product option in Shopify and disconnect the metafield, then enter the option values manually (for example: Size, Color, or Material).
Learn more about metafields in Shopify’s documentation.
Alternatively, you can switch to Custom Pricing version that does not create additional variants such as Standard Method (V2) or Accelerated Method (V3). For more information, please visit Discount Methods and How to Switch.
