How to I obtain 'Download' plugins?

On my WPMU DEV dashboard I see some plugins which are listed as 'Install' and some plugins that are listed as 'Download.' The install plugins work fine when I select them but whenever I select any of the 'Download' options (such as 'WP for iOS' or 'WP for Android', it treats me as though I have no license and must 'repurchase' the entire package.

How do I obtain these plugins as a member?
