UDT Bug for DisplayPath in Alarm?

Hi, I have some problems copying UDT.
If I create a new UDT instance, the displayPath in alarms will work, but when I copy this UDT instance and rename the instance to a different name. Even after I updated the parameter for the UDT, however, the displayPath in alarm didn't update and still have the old name that I copied from. Is this a bug or did I do something wrong?

Was the alarm active when you copied the UDT?

Have you tried turning the alarm off and on?
