Click Edit supported devices on the next binary. Because two binary files for the same app can't be installed on the same device, the devices supported by the first binary are unable to be selected. If you hover over the help icon for those devices, the message "Targeted by another App file in the current version" appears. Targeted means that you selected support for the device with your app. With the second binary file, you can select support for devices not already selected by the first binary.
