I am trying to wrap my mind around place_hierarchy lists. I am having two issues:
1) By default (at least with DC as underlying template), there is a list "DC Coverage Authority" under place_hierarchies. Unfortunately, I am entirely unsure as to how to use this list. At some point I must have been able to add concepts to this list as they show up in the "Related Placed" box under Relationships. However, they do not show up in the browser hierarchy and it is unclear to me how to add to this hierarchy. So, either I do not understand how this hierarchy is used or there is a bug.
2) As a way around this, I decided to create a places hierarchy of my own (I guess that would be a CA-internal list) as a sibling to the DC Coverage Authority list. This works fine in the hierarchy browser. However, when I now go to the "Related Places" box for an item, every element of my hierarchy is displayed on the root level. In other words, there is no hierarchical organization. Yet, whereas the label "DC Coverage Authority" shows up in that same list, the label for my list does not show up at all. Again, am I doing something wrong or is this a bug?
BTW, I am on 2.7.11 with PHP 7.4 (FastCGI).
