If you would like assistance with completing a hierarchy for Advanced roadmaps (Portfolio), please send to support@eazybi.com more information about your hierarchy (screenshot with Hierarchy levels of Advanced roadmap from Jira administration -> Manage apps -> Advanced Roadmaps for Jira -> Hierarchy configuration) and we can help you with building the hierarchy.
