Having read the documentation around managing my boards, I don't seem to enjoy the benefit of items in the "done" column disappearing after 14 days as per the rules that govern the KANBAN board layout. I did convert my board at one stage to a Sprint because it didn't clear according to this rule and then completed the sprint (I think) but am still unable to see my tasks that are in a DONE status from clearing, either when wanting to perform a "release" as per Sprint rules or as indicated under "KANBAN".
