I am using sprint grouping for my schedule, but when I move an item to the next sprint and the previous sprint is still listed on the JIRA issue, the JIRA issue will show up twice, once in the open sprint and again in a section for the closed sprint. I dont want to see the closed sprints in the my structure, it makes it too big, intorduces duplicates and makes the dependencies look really messy in the chart and hard to follow, how do I get rid of them?
