How do I change what is shown in the left column of CloudKit Dashboard?

In the Default Zone view, Apple is shows the "title" field in the left column for each record even though the address field is listed first (it annoyingly lists everything in alphabetical order). How did they do this? Mine always lists the first field (which in this case is a field that has no data in it currently) in the left hand side which makes it very hard to quickly find a record at a glance.
