Upload products from CSV

I upload all my products to my shop from a CSV file import. I add the product markup into the a custom field in the csv. It add the markup percentage to the product field but don’t update the shop with the sales price, I need to open each product and select update/Publish to update the shop to the correct sales price instead of the cost price

I use the free version because my shop is new and I cant afford the plugins at the momen
