Charecteristic imported accidentally

Hello.
Client imported a csv and after that the 80% of products have a characteristic with no other values. No chold products .
Can you please tell is where this information is kept so that we can delete it. I cannot find the characteristic "sockssize" in the products table.

Hi,

This indicates that you have an entry linking the characteristic with the main product in the hikashop_variant table without an entry linking one of the values of that characteristic with the main product in that same table.
