We cannot even change the displayed tab in the record properties because it gives the error. When I customize the search results pane to show the "related record" and "related records" fields, both of them display nothing for the affected record. Is this record broken or is there another way to resolve this issue?
It ended up being a chain of "related to" and "alternately within" relationships that Trim ended up not liking. We were able to remove the relationships to modify the record metadata, but we have reason to have it the way it was so we re-established the relationships afterward. HP may want to consider changes to Trim to prevent the client from creating relationships that it doesn't work with.
