I uploaded my app to the App Store using xcode. I can see my build in my existing app on iTunes connect. However when I want to add the build using the "+ Version or platform" option it shows me a disabled iOS button:

My build version is 2.0.

I received an email from Apple stating that the app completed processing. Any reason why I can't select it?
