Why are some Android APIs not showing up in the AVD Target Audience tab?

I have to work in an environment that has no internet connection due to security reasons. I have downloaded the latest APIs and followed these steps in the following answer: have in my

..\adt-bundle-windows-x86\adt-bundle-windows-x86\sdk\platforms

      

        
        
        
      

    

Update Android SDK manager without internet connection, but earlier download for a different SDK

At the top, I can see the APIs in the SDK manager as set, when I go to the AVD manager, they are not shown in the target.

Only Android 4.2 API came out (which comes with ADT / Eclipse (Android Developer Tools) preinstalled. But I noticed that in SDK Manager it had two files (SDK Platform and ARM EABI v7a System Image), while others there was only the SDK platform file.

Please advise.
