SA Project - Alarm Page Strange behavior - after Runtime Restart

Hi,

Alarms are configured as Time Stamped Alarms, I have one variable tag that trigger the alarm and one variable tag holding the timestamp for the specific alarm tag. 

The communication to the controller is OPC. 

If I restart the Citect Runtime (without doing any changes to the project, nor do I re-compile), then if I generate an alarm the alarm is displayed in the alarm list. If I then generate a second alarm, this new alarm will overwrite the previous alarm, it will not be listed above the other. The alarm acknowledge is also inactive for these new alarms. 

The only way to get every thing reset and working as normal is to stop Runtime again and do a new compile and then start the RuntIme again. 

I don't expect that we need to compile the project before each time we do a RunTime start?

Any idea whats going on?
