I can see the fields on "add to cart" form, but not in the checkout page

Please ignore.

Hi,

I can see the options when I'm on the product display node.

After I select the option and click on "add to cart", I then proceed to the checkout page.

The options are not visible there.

Also, there is nothing stored in the DB.

INSERT INTO `commerce_option` (`option_id`, `set_id`, `product_id`, `field_name`, `field_delta`, `line_item_id`, `created`, `changed`, `data`) VALUES
(2, 'location', 2, 'field_location_cart', 0, 4, 0, 0, NULL);

As you can see, the data field is empty.
