When creating a Taskboard why are the plan items removed based on the status columns I want to show?

If you create a taskboard plan view and let's say an Epic or Story has a status of Pacakge for Production.  A task's workflow has New -> In Progress -> Done just as an example. 

Why do I need to select the Package for Production as a status column?  If I only select new, in progress & done the stories assigned to Pacakge for Production status will disappear.  There is no reason to have the package for production status as a column, since the Story (plan workitem) is not actually moving within the taskboard, just execution items.  Am I missing a setting somewhere?  I don't want to show columns that have no meaning to the execution items that are being shown.

To me this is a bug and all stories should be shown that are assigned to the current sprint or have a linked workitem in the current sprint.  To take it a step further an additional filter option could be added to only show stories in a certain status.
