Csv Import Quantity Discounts

Hello All,



I'm using cs-cart 4.1.1 and i'm having some difficulties uploading quantity discounts.



After uploading, the quantity discount and price is not showed in store front.



if i open a product in back office the quantity discounts are available and if i save the product it shows correctly in store front.



Is there a way to upload and make discounts available without going throw each product? They are quite a few.



Thank you in advance.
