I have the problem with task from one project. Their back to the backlog although when I'm closing the sprint I'm chosing "move to a new sprint" option.
This applies to all tasks in this project - which every status (done/closed or to do/in progress).
We have one sprint to all project in Jira. The project is in filter with board, where the sprint is active.
Could you tell me what I should do to resolved this problem?
