Why products are not displayed correctly on my PrestaShop store after migration?

In case your current e-store products are associated with combinations, you should check whether the product has the EAN13 field and the PrestaShop store configuration (Route to Products) contains the field *{-:ean13}*.

If Yes - it is recommended to delete the *{-:ean13}* field from the configuration. This will help to display the products on PrestaShop store properly.
