InSalesforce Loyalty Management, visibility issues of components such as the Loyalty Members Profile Cards on the Lightning Record Page can often be traced back to configuration settings related to the Loyalty Program itself. While options A, B, and D mention various dashboards (Member Summary, Member Preferences, and Member NPS), these are not directly related to the visibility of profile cards on the Lightning Record Page.

The correct setting that is likely missing and preventing the visibility of the Loyalty Members Profile Cards is the configuration of the Loyalty Program as Primary. This setting is crucial because it defines which Loyalty Program is considered the main one for the organization. Without setting a Loyalty Program as Primary, Salesforce might not properly display related components, such as the Loyalty Members Profile Cards, due to a lack of context about which program's information should be displayed.

In Salesforce, the concept of a "Primary" program is used in various contexts to denote the main or default record among multiple. Similarly, in the context of LoyaltyManagement, setting a Loyalty Program as Primary ensures that its related data and components are given precedence and are properly displayed in the user interface, including onLightning Record Pages.

For reference, Salesforce documentation on Loyalty Management typically covers the setup and configuration of Loyalty Programs, including how to designate a program as Primary. Although the exact steps can vary based on the Salesforce release and customizations, administrators typically need to navigate to the Loyalty Management settings or related setup area, find the specific Loyalty Program configuration section, and select an option or checkbox to designate a program as the Primary Loyalty Program for the organization.
