Further, it looks like the code itself probably contains “@package Joomla-1.0.0″ tags in some docblocks, resulting in the visible “Joomla-1.0.0″ package.

As for the “Joomla 1.0.3″ heading in the top right, that appears to be a package name that is _not_ used by any package tags in the code… otherwise you’d see it listed in the package name list the goes across the top of the screen. At first I thought maybe it appears there due to usage of the “–defaultpackagename ‘Joomla 1.0.3′ ” runtime arg, but if that were true, I don’t think a package named “default” would exist. Though, if the code itself did use “@package default” somewhere, then it probably is that runtime arg causing the “Joomla 1.0.3″ to appear.

Hope that helps…
