A "series" in a bundle is really just a column vector -- with no metadata -- that can be turned back into a series when pulled out of the bundle under the right conditions. (And a "list" in a bundle is just an array of integers that can be turned back into a list if conditions are right.) To preserve series metadata in a bundle would require that the "series" itself be stored as a bundle (numerical values plus attributes, perhaps including an array of strings). This is something that one could implement at the hansl level but there's no built-in support for it -- though I guess that could be a feature request.
