I'm going through the "How to upgrade your URLs" documentation. I've downloaded a .csv and made the changes. I'm no longer needing to track anything, so I just have the final URLs. When I upload and preview I'm getting an error: "The value in column 'Ad type' is invalid. I haven't changed those fields. They still read "Mobile app install ad." Is the problem that I need something in the "Tracking template" column? I just checked and 'Ad Type' is still in the same column "X."
