I'm walking through all the documentation I've found here in order to build a hierarchy that will allow me to group Epics across Projects for enterprise reporting purposes. Whenever I go into Advanced Roadmaps Hierarchy Configuration, something is stopping me from re-ordering the levels so that an Epic is subordinate. I've used the out-of-the-box Capability issue type and created my own Initiative type. I can order any issue type I've added in, but only below the Epic.
What am I doing wrong?
