I'm having issues getting embedded data to show up on an insight.  

I optimized the properties for reporting, and they are showing up under 'Available Fields' in Explore Data, so I can add them as columns to a table.  But, when I add them as columns, the data is showing as blank (even though I know there is data there). 

If I generate a report definition and add a declarative index join for the embedded data and run the report, I do get data back.  

Does anyone have pointers on how to get this to work?  Do I need to create an association?    

When I look at some of the help content, it makes it seem like you just have to optimize the fields for reporting and it should just work:  https://support.pega.com/discussion/some-insights-insights-and-explore-…

Thanks in advance for your help.
