Our "fix version/s" is comprised of issues from our backlog (contained in Project 1) and issues arising out of our production environment (contained in Project 2).
We just upgraded to JIRA Software 7, and are excited about using Boards for ranking and sprint planning.
However, when I expand the VERSIONS tab on the left side of a Scrum board, I see that the issues belonging to the same version, are divided across 2 projects.
It is not desirable to plan sprints for each project, when in effect, the issues belong to the same version.
