Sub-Task view with epic filter at core board

Question

Hello,

we are using the sub-tasks a lot, so at the board view we use the "Group by->sub-task". Now, we only want to see the tasks and sub-tasks for one epic, so we use the given filter and select the required epic. But doing this, only the tasks without sub-task, which belong to the selected epic, are shown. But the tasks, which belong to the epic and have sub-tasks, are not shown. And of course the sub-tasks are also not shown.

I gues, the problem is, that there is no connection between sub-tasks and epics and if "Group by->sub-task" is chosen, tasks with sub-task don't have influence on what is shown.

Does anyone has a solution for this problem or is this a bug?

My expectiation would be, that with active "Group by->sub-task" and selected epic filter, all tasks belonging to that epic and also their sub-tasks are shown. So there also would be a connection between the sub-task and the epic.

Since I am not able to replicate the issue in my environment and nobody else has responded, I would recommend that you contact Atlassian support directly. With access to your instance they may be able to discover a setting that needs changing or determine if it is a bug.

Tried on different boards with different epics, with different assignee and without, it's always the same. If I use Group by>Sub-Task and activate an epic filter, all Tasks with sub-tasks dissappear, even if they belong to the selected epic. So the Group by>Sub-Task is useless, but also needed because we use a lot of sub-tasks.

Epic, all Tasks and the sub-task are assigned to me (so all the same person).

I just tested it without the assignee filter and the result is still the same for me, I still don't see the task with the sub-task.
