We have next planned sprint created, and then we move defects from current sprint (to be closed) to new sprint.
What exactly happening is, 2-3 defects are not getting moved to new sprint even after having in progress state and not going back to backlog items as well. Those 2-3 defects will stick back to closed sprint and remain in progress.
We want to understand what exactly we are missing or any pre-defined criteria which we are missing and hence this is happening.
