Members not listing under the Groups

I've configured Keycloak with our AD server using the LDAP provider for user federation, and we can retrieve all users, regardless of their group membership. However, when I navigate to "**Groups**" in the Keycloak UI, no groups are listed. After creating a mapper with the type "group-ldap-mapper," I can see all the groups. Despite this, when I select a specific group, its **


**, even though I’ve confirmed the user exists in AD.

Has anyone encountered a similar issue or have any suggestions on what might be missing? We are using Keycloak version 22.0.2.
