Issue

Preconditions:

Magento Commerce with simple products.

Steps to reproduce:

1. Go to Quick Order on the Storefront (while not logged in).
2. Enter a valid SKU, click the product that shows up in the autocomplete field, and set Quantity = 1.
3. Enter the same valid SKU, but change the case (change uppercase to lowercase, or change lowercase to uppercase) of the 1st character, and click the product that shows up in the autocomplete field, and set Quantity = 1.
4. Enter a random_sting_value for SKU, and set Quantity = 1.
5. Set SKU = 123123123, and set Quantity = 1.
6. Delete everything except the 1st entry you added to the Quick Order page.
7. Enter the 1st SKU (similar to Step 2 above) in the Enter Multiple SKUs field, and click Add to List.
8. This results in a quantity of 2 for the 1st SKU and a line for a random_sting_value.
9. To test more, refresh the page.
10. This results in no SKUs for quick order, as expected.
11. Enter a random_sting_value2 into the Enter Multiple SKUs field, and click Add to List.
12. This results in 2 valid SKUs from before and a random_sting_value2.

Expected results:

Two or more products are able to be added to the cart, as expected.

Actual results:

When taken to the Cart page, the 1st added product appears normally, but for the 2nd product and any subsequent products added to the cart, a "1 product requires attention" error message appears. The 2nd or any additional products will be listed on the Product Requires Attention section of the Cart page.
