Relationship-level Power Lists

Good Afternoon-

I've hit quite a snag.  I'm attempting to build my first Relationship-level Power List in Journey Orchestrator/Outreaches and having issues getting anything to populate.

Create Power list for: Relationships --> Products
Derive list of recipients from: Data Space --> Products Relationship Contact --> Email Field --> Contact Email

I started by putting in a criteria of:

Account Name: Equals: CareerArc (our company and my testing account)

Nothing populated, so I deleted the criteria.  I then tried: 

I tried Contact Role: Equals: Day-To-Day Contact - SR

Nothing populated, so I deleted the criteria.  I then tried: 

No criteria

Nothing populated.

I checked my DataSpace of "Products Relationship Contact" and found that Contact Name, Account Name, Email Address, Contact Role, etc. were all mapped, however nothing populates.

What is happening?  I'm assuming that the data isn't flowing into the DataSpace, however I cannot figure out how to see the data contained in the DataSpace, nor can I find the Objects that the DataSpace is referencing.

Any help would be greatly appreciated.  People who have had similar issues.  Pointing me in the direction of tutorials that I may have missed (I've been reading what I can find on Community and on GainsightGo to no avail).

Thanks
