1. Summary of the problem.
ADCIO-1745 has 3 subtasks (ADCIO-1746, 1747, 1748), but only ADCIO-1748 is showing up on list view.
FYI, ADCIO-1748 is cloned from ADCIO-1747 and modified description.
2. Details of the problem
The above Backlog is "custom made" backlog board from saved Filter not the pre-built backlog board of project.
All the tickets (issues) are created from Team managed project and the team managed project Backlog does not show any subtask (child issues) and it looks that is the default behavior.
The below is the default Backlog of team managed project. It shows only icon and no way to expand child issues.
So we tried custom Backlog board based on saved filter and it has the above problem, ie., only cloned subtask is shown.
