Document the behaviour of adding certain statuses to a filter on Scrum board

If a filter has certain statuses excluded, for example the below, it will break the chart calculations.

project in ("WRM", "WP", "TOOLS") AND ( status not in ("Complete", "Closed") OR Sprint in openSprints() ) AND issuetype in standardIssueTypes() order by Rank ASC

The planning board will exclude issues in the right-most (eg Done) column as per Using Plan Mode. This means there isn't a need to exclude those issues using a filter, as their status can be dragged to 'Done'.

If they are excluded, when chart calculations such as the burndown chart are done, it will break the charts so they don't appear correctly as per the example screenshots.

I wasn't sure of the best place to put this, it should be in the core docs rather than a KB but not sure where.
