When the sprint is closed and start new sprint, all the completed issues transfer to new sprint somehow. Even the issues are on the 'Done status', Jira doesn't consider it as the 'completed issues' when I complete the Sprint.
If I combine all the 'Done status" in one, the completed issues don't transfer to new sprint when I close and start to a new sprint, which is correct.
I didn't have this issue last year, but sprint or workflow is not going well this year even I didn't change any.
Can anyone please help?
