Alarm not coming in the list in 800xA system

I am facing problem with one of the PLC controller PM861A, the alarms are not coming in 800xA alarm list. But if open the phase plate for transmitter or motor the alarm will be appearing inside with red indication. Also no sound is available when it is generating. The alarm was working before and this happened after power failure and memory gone . After i downloaded the back up again to the controller and then the alarm issue started. I create even new alarm and still same issue. The other PLC controllers connected to the same 800XA is working well with proper alarm.
