One of our teams has a "No Plans to Address" status which is mapped to resolved Resolution type of "Won't Do". That status is also mapped to our board's Done column.
Recently that team's Product Owner has been trying to do some backlog maintenance by clearing out a lot of items that we just won't be getting around to doing. However, what he's seeing is that those items do not show up in the project's Cumulative Flow Diagram as belonging to the Done column, even though that's where the status is mapped for the board.
This shows to a growing gulf betwen To Do items and Done items which isn't what we want. We'd like to be able to use this report as a way to monitor the health of our teams' backlogs.
Any tips on debugging or ideas on why this may be happening?
