When trap source IP address is found on multiple devices in Spectrum all devices with the IP receive the alert

Traps received from IP addresses that are shared between devices, but from non-management addresses are asserted on all devices.
Is there some other criteria or additional comparison criteria to avoid this duplication of events (and erroneous alarms)?
Release : 10.2.3+
Component : Spectrum Core / SpectroSERVER
Introduced new device attribute UseRPAForTrapProcessing (0x13369) in Spectrum Server 10.2.3 that enables use of the Redundancy Preferred Address (RPA) (0x12d84) list instead of the DeviceIPAddressList (0x12a53) for processing traps.
This allows devices to be configured to excluded IPs from trap processing.
IPs that are in the Redundancy Excluded Address (REA) (0x12d85) List, are not included in the RPA list and therefore do not participate in trap processing.
This functionality is disabled by default, setting UseRPAForTrapProcessing=TRUE enables it.
As part of this change, non-global (link-local, site-local, and so on) IPv6 attributes are also excluded from trap processing.
This device attribute was added in Spectrum Server 10.2.3:
