On NYSA there is a List metadata element called "Non-unit aggregation". It is rendered as a type-ahead lookup. During the data import, the values were set using a listItemSplitter and the data was imported properly. You can view the relationships from any "Summary" screen or search results Display. However, in the actual UI screen where the element lives, the bundle appears to be blank.
See attached screenshots - both of the same record. In Summary, you can view the value. In Basic Info, you can view the blank bundle.
There are no Non-unit aggregation elements on the record you reference. It's correct to be blank. I verified this in the raw database. In the summary display you're showing related list items as "Non-unit aggregation", not the metadata element.
