App Store Issue - iPhone 5 Optimization Requirement

I got the following message when I uploaded an app to the app store:

"We have discovered one or more issues with your recent delivery for "........". To process your delivery, the following issues must be corrected:

iPhone 5 Optimization Requirement - Your binary is not optimized for iPhone 5. As of May 1, all new iPhone apps and app updates submitted must support the 4-inch display on iPhone 5. All apps must include a launch image with the -568h size modifier immediately following the <basename> portion of the launch image's filename. Launch images must be PNG files and located at the top-level of your bundle, or provided within each .lproj folder if you localize your launch images. Learn more about iPhone 5 support and app launch images by reviewing the iOS Human Interface Guidelines and iOS App Programming Guide.

Invalid Launch Image - Your app contains a launch image with a size modifier that is only supported for apps built with the iOS 6.0 SDK or later. "

I added an additional image to the "Included files" in the "Air for iOS Settings/General" menu. The file is called "Default-568@2x.png". The file is included along side "Default@2x.png" and "Default-Landscape.png." These images all represent the splash screen.

I thought this would solve the problem but it did not. Does anyone have any thoughts? Did I the file named incorrectly?

FYI, I am working in Flash Professional CC.
