Summary

• In the Release Burndown report, if the "Active" period of two or more sprints that contain issues under a given Version overlap, all issues will be displayed under one single, latest sprint.
• Having multiple overlapping Sprints on a single Agile board can happen if:
  • "Parallel Sprints" is enabled;
  • The board contains issues from other boards;

This issue also affects Epic Burndown.

Steps to Reproduce

With "Parallel Sprints" enabled

1. Enable "Parallel Sprints", as described here;
2. Create a project;
3. Create a version under that project;
4. Create a board with all issues from the project;
5. Create two or more Sprints, associating one or more issues of the board per Sprint;
6. Estimate all issues and set the created version as "Fix Version" of the issues;
7. Start all created Sprints;
8. Close one or more issues in each Sprint;
9. Complete all Sprints;

Starting Multiple Active Sprints without 'Parallel Sprints'

1. Have an existing board (Board 1) with a filter showing: "project = SSP ORDER BY Rank ASC"
2. Create a second board (Board 2) with a filter covering just a limited set of issues in the SSP project: "issue in (SSP-1,SSP-2) ORDER BY Rank ASC"
3. Now start a Sprint in Board 1, then Board 2
4. Refresh Board 1, notice that there are two active Sprints showing

Expected Result

• Release Burndown report will show list of issue respectively to its own sprint

Actual Result

• Release Burndown report shows all the issues under the Sprint last closed.
  
  

Workaround

If due to Parallel Sprints

• Avoid using parallel sprint as this is still under Labs which is not stabile and to be supported
