I have a structure in an instance of enterprise Jira that includes "Advanced Roadmaps for Jira".
Currently I am grouping by "Parent Issue from Advanced Roadmaps(Portfolio) for Jira"
This works fine, and shows a heirarchy of Themes > Initiatives > Epics.....unless the initiative is completed, at which point it "detaches" them visually from the parent theme. Setting the initiative back to In Progress "reattaches" it back to the parent theme.
Any insight on why this is occurring and how to correct?
