If the "Group View Mode" is set to "max", then alerts are grouped and, based on the criticality of the grouped alerts, and alerts of maximum severity in any group are shown in the client. If the value is set to "latest", then alerts are grouped and, from the grouped alerts, the latest updated alert in a group is shown in the client.
