Environment:

Your OpenProject Version: OpenProject 10.2.1 (PostgreSQL)
Windows 10 / Chrome / any:

Steps to reproduce:

1. Create Main Project
2. Create several subprojects
3. Add feature/tasks in subprojects
4. Go to page Backlogs in Main Project

Actual Behavior

On backlogs view in main project you can see all versions ( sprints and product logs ) but you can't see tasks/features/eipcs etc which you have created in subprojects

Expected Behavior

In main project backlogs view you should see all tasks from subprojects and be able to drag and drop task between versions

Anyone has found solution for it ?
