On Magento, there are two products "Not Listed" and the others look like they have some kind of alert "!". Are the issues with the "Listed" ones resolved? How can we resolve the issues with the "Not Listed"?
You have to review the errors or warning associated with that product. Often it is a missing piece of information, such as a missing UPC that is required or something else that is easily corrected from the Razor or Magento applications. When in doubt, use Google to research that error that you are receiving.
