On the KHF system, there is a metadata element called condition_notes. In the UI, it appears to be a text field, and there are several object records with data in this element.
However, viewing the element from Manage - Administration, I see that it's actually a container with several sub-elements.
But in the User Interface, it appears in the editor as a text field. (See New - Object - Publication).
When I export the profile configuration and install it on another system, the container appears correctly. But even when I remove the element from the UI and re-add it on the KHF system, it still appears as a free text field.
Not sure how this happened, but since data exists already, my guess is that it is supposed to be a simple text field.
The problem is, I can't import to it since it's technically a container with sub-elements.
There was a discrepancy in the configuration data in their live system. It's on an early metadata element, one from the original configuration, so who knows when it got that way. I reset it and condition_notes are showing appropriately again.
