I'm not sure if this is expected behaviour or not, but it is causing some confusion for our users:

If a story is closed in the current sprint, it no longer shows in the schedule, and is removed from the capacity calculations. It's still visible in the scope section. This is problematic for us, as it then appears that there is available capacity in the sprint, when that's not the case.

To address this, issues that are resolved in a sprint should continue to be visible in the schedule and they should continue to count towards the capacity utilisation for the sprint.
