I'm following the video on YouTube which takes me through the steps to update the product attributes spreadsheet. I enter the cost price of a product and sale price then click on save and close the spreadsheet to return to my products table. I click on the "Update product attributes" option under "Edit" and then, no matter how many times I've tried this process the product is added without the cost price or sales price (or any other attribute I assign).

Can anyone here explain what I am doing wrong?
