Regarding "2.Epic" of "Group by" on My work screen of Tempo does not work well

[Tomoya]

I use Tempo in conjunction with the next-generation template.

In addition, issues are managed in the hierarchical structure of project> epic> task> subtask using issue types.

I want to display the sheet with the above structure in Tempo as well.

The grouping of "2.Epic" is not working well, and the four-level structure is not displayed.

Is this behavior correct? I want you to tell me.
