We've had our Jira Cloud environment for over a decade and some of our Spaces (formerly Projects) have stopped being used and had their boards deleted. However, some of the Sprint values that were created for those spaces are still floating around in the Active and Future sprint values on the sprint dropdowns. We need to clean them up. Just hiding them with "only show sprints for this project" is not sufficient. Where can I complete old sprint values to get them off of our dropdown list?
