Steps to reproduce:

1. Add host "Testhost": template ICMP Ping (as supplied in Zabbix 6.4.0beta4), agent interface 1.1.1.1
2. Wait like 1 minute
3. Go to Latest data for "Testhost"

Result:

No ping data is saved.

Errors in server log:

  2725:20221217:204500.570 item "Testhost:icmppingloss" became not supported: Ping item must have target or host interface specified.
  2725:20221217:204500.570 item "Testhost:icmpping" became not supported: Ping item must have target or host interface specified.
  2725:20221217:204500.570 item "Testhost:icmppingsec" became not supported: Ping item must have target or host interface specified.

The same is shown in Latest data: "Ping item must have target or host interface specified."

Expected:

Basic ping monitoring is started and runs successfully with the supplied template.

Also note:

If a new item is created as icmpping[\{HOST.IP}], it works fine.
