I created a user story and its sub-tasks then cloned it. Both stories were in the backlog at first, then I moved them to a sprint. The original went to the sprint and stayed there, but the cloned one keeps coming back to the backlog.
I tried adding the sprint in the detail view, dragging it to the sprint, and right-click MOVE TO the sprint - same thing.... it let's me do it - no errors - it will show in the sprint, but as soon as I refresh the page, it's back in the backlog.
The History only shows the "move to sprint" actions - not the "move to backlog" action.
I'm in a NextGen project.
