Hi!
We have a little Problem with our sprints. Everything is working so far except once we complete our sprint and start a new one not all of our unresolved issues are moved to new sprint. We have the following workflow satuses:
To-Do:
- Open
- Waiting for Information
In Progress:
- In Progress
- In Review
- Waiting for Approval
Done:
The normal Workflow with all transitions is working fine, and all issues from To-Do and In Progress states are moved to new sprint, except the "Waiting for Approval" state.

We checked all different kind of configurations but we do not have any clue why only this specific status is not moved to new sprint.
Maybe somebody have a hint or a clue for us 
Thank you in advance!
