Exploration with Package not showing Query Items across Query Subjects

[B.C.]

Hello and many thanks in advance for your response. I have a Framework Manager Package with multiple Query Subjects with relationships in a basic star schema... 1 fact table (Query Subject). These relationships in the FM Package are in the Physical View. It's published to Cognos Analytics as a DQM Package, I've ran the Enrich Package process, and reports and dashboards seems to be working as expected (underlying relationships are working). But when I create an Exploration, under "Explore relationships in your data", it's not showing any related Query Items outside of the Query Subject with which I've chosen my "field of interest". It doesn't matter if I choose a fact or attribute for my field of interest in any Query Subject, relationships across Query Subjects are not shown. Does anyone have any idea what I might be doing wrong here? I've been tasked with presenting Cognos AI functionality to our enterprise and I can't seem to get past this.

Thanks again in advance for all the knowledge from the gurus here.
