When a sprint is closed and issues roll into the next sprint or to the top of the backlog, they are still associated to the completed sprint. The sprint name is listed in the Sprint field. Seems like an issue can only be completed or counted in the sprint the issue was closed in. If the Sprint field cannot be modified, how do we determine which sprint the issue was closed in? also how to not include this issue when searching from issues completed in the 1st sprint?
