We have 2 sprint teams, one on-shore and one off-shore, that work on an alternating sprint cadence. We recently made that change and split the sprints up. When I created the separate projects and sprints, I added the respective sub-projects, in which some are relevant to both teams. Now on each teams project page, under active sprints, there are both and you have to filter among them. Can I delete the irrelevant sprint from the project without deleting it entirely?
