When searching the group membership for groups, only the Security tab is available. The Members, Member of and other tabs are not visible on the Active Administrator server but could possibly be visible on other machines.
RSAT(Remote Server Administration Tools) must be installed on the server to view these settings.
Open the Server Manager tool in Windows and go Add Role and Features. Go through the Features and add RSAT taking the default settings, then install. Once completed, close and reopen the console to check if the information is now visible. Although not required a reboot is recommended.
