From snapshots it appears that you have connected event list in alarm band, only alarm list is supposed to be connected in alarm band.

Hi,
Check the OPC status, AE part for that controller and if the controller is properly connected to the control network. You have to find yellow smiling icons in both tabs of OPC Server for that IP address.
Also check Alarm Service status in your system.
