I'm using the statistic burndown chart with story points (daily). I have my version setup with multiple child versions (as my sprints). Since the project is quite large, I imported almost 500 issues with about 200+ of them being closed.They are in the current version I am trying to burndown. I've been closing stories but my burndown is almost flat and I cannot figure out why whatever I do doesn't impact the chart. Anyone have any ideas?
UPDATE: I should add that I have "released" all the old closed issues that I imported after adding them into child versions.
