I have three Sprint boards. I often "Create a Sprint" and add jiras to them and leave them in that state for a day or two before I finally start the sprint. If I have multiple such unstarted sprints, the JIRAs in them often get mixed up. One of the sprints will disappear and all the jiras I put into that one will show up in another unstarted sprint.
Can I only have one unstarted sprint at a time? or this is a bug in greenhopper?
