Current Behavior

Trying the following code,

var subscription = new Subscription();

MonitoredItem monItem = new MonitoriedItem((uint)1);
monItem.StartNodeId = NodeId.parse("ns=2;i=1001");
monItem.AttributeId = Attributes.Value;
monItem.SamplingInterval = -1;
monItem.DisplayName = "NodeItem1";

subscription.AddItem(monItem);

Now, am trying to change MonitoringMode to Disabled,

monItem.MonitoringMode = MonitoringMode.Disabled;
subscription.ApplyChanges();

Though we have changed MonitoringMode to Disabled, still we are receiving notifications for that particular monitored items from source.

Expected Behavior

Expected behavior is that subscription should work properly and it should not receive notifications from the mentioned monitoring item.
