To reproduce, have this sender.conf file (think it's agent's conf file):
ServerActive=127.0.0.1,127.0.0.1:10061 Hostname=it0
Have 2 zabbix servers running. In current example locally, on different ports for trappers (default 10051 and 10061), but it does not matter. The same happens with 2 separate servers in network on different IPs.
sender v6.2 works fine:

So, only one zabbix server actually received the value, which is very firs in the ServerActive list.
Everything is compiled from current 6.2 and 6.4 sources.
zabbix_sender v6.0 also works fine.
