We work in JIRA DOT
Hierarchy Levels - Advanced Roadmaps - Jira
We are trying to configure a new hierarchy level in Advanced Roadmaps (JIRA DOT), but facing several issues:
1. We are unable to configure new hierarchy levels (see items 1, 2, 3).
2. Existing hierarchy levels (those without numbers) appear to be not editable — for example, we cannot deselect "Epic".
3. It is not possible to associate the issue type Feature with the hierarchy configuration.

Goal:
We want to introduce an additional hierarchy level — Feature — between Epic and Story.
Request:
Could you please assist with the configuration? Specifically:
- Which actions are required to add or configure hierarchy levels?
- Is this behavior expected, or are we facing a misconfiguration?
Internal Analysis:
Our internal JIRA DOT support provided the following statement:
"Unfortunately, your issue is related to a plugin (even though it is now part of Jira, it was previously a paid plugin), namely Advanced Roadmaps for Jira.
We are not familiar with the plugin in detail and cannot identify the issue.
We recommend contacting Atlassian Support directly.
Also, after checking other Jira instances, we observed the same behavior. It seems to be a default configuration, and further guidance is needed to understand how to achieve the desired setup."
