Overview:
Only one Vault Clinical Study appears when the user uses the Product object view.
Root Cause:
The Page Layout in the Product object configuration shows a simple join of Product Clinical Study > Clinical Study configured for the related object in the Clinical Studies section.
Solution:
The solution is to modify the Clinical Studies section of the Product page layout so that it reflects Clinical Study. This allows all associated Clinical Studies to appear when viewing the related Product object record.
