The SNMP poll asks each device's sysName in the same GET and keeps it (snmp_003_sys_name). A syslog source told apart by name finds its own address from the SNMP device (reported or given name) or host of that name, so its lines reach the SNMP device's and host's pages again; the edit page gains Device address, which always wins (syslog_004).
