AnyChange Alarms getting triggered when powering up the system

Hi,
I have an UDT instance with over 200 child tags with Change alarm with AnyChange Mode associated with almost most of them.

All the alarms are getting triggered when I power ON my ignition edge PC. How can I make the alarms to get activated to any changes in tags once I’m powered up and ready.
I’ve tried adding delay to the enabled of the alarm and use quality of the tag as a binding option. Still, the alarms are triggered once the delay is over after the power up.

The system ready is activated using a gateway start up script with a delay of 5 minutes.

Thanks in advance to all the help.
