Relation preview when adding in Component

When a Component has a Relation field pointing to a Collection (Content_block in this case), and I add the Component to a Dynamic Zone, the selector shows a preview of one of the fields on the Collection entries. In the screenshot below it is picking a veird field to show in the preview (“Category”, “foobar”). Can I change what field is shown there? What is the criteria for selecting what field to show??
