It’s not clear to me if you are referencing the auto-report formats that you set in a map’s config, or the contents of a Report Action piece trait. Can you supply screenshots of which things you’ve configured?
For instance, I don’t believe you can get user-defined piece properties to appear in the reports generated by the multiple “Auto-report format for…” lines in a map’s configuration. You’d have to do some jockeying to temporarily copy the values into a Global Property. Some background here.
