Issue Summary

The next-gen "Group by" feature is not displaying the swimlanes in the issues' order.

If you compare the order of the issues in the backlog view and in the Active sprint view when the "Group by" option is defined by Sub-task, Epic or Assignee, the order of the swimlanes don't follow the pattern of the backlog view (Rank)

Environment

Jira Software cloud

Steps to Reproduce

1. Create a new Scrum next-gen project
2. Add stories to it and sub-tasks to some of the stories, or add Epics to the roadmap and Stories under it
3. Access the Board view (active sprint view) and in the Group by options menu select Subtask or Epics
4. Compare the order of the issues in the active sprint view with the backlog view

Expected Results

The order of the issues should be the same in both views

Actual Results

The order of the issues is different:

Notes

Workaround

Create a Classic board and edit its filter to return the next-gen issues.
