I completed a sprint, active tickets were moved to the new sprint correctly. The new sprint was 'started'.
When I look at the Backlog list, only the active tickets appear against the new sprint.
When I look at the active sprint board, All of the Done items from the previous (closed) sprint are still displaying.
Sprint reports show the tickets are allocated to the correct sprints.
How can I get the done items out of my active sprint board? This has only started happening this week.
