Hello
I am trying to generate a report that shows me all of the tickets that are assigned to future sprints. I am doing that by the following JQL " resolution is EMPTY AND sprint NOT IN closedSprints()"
My issue is - If a ticket was previously assigned to a completed sprint, the ticket won't show up in the report. When i look in the ' sprint' field ( see screenshot below) , i can see multiple completed sprints.

How can i clear the ' completed' sprints, and will it have any impact on other reports?
