Steps to reproduce:

1. Create Host
2. Assign template
3. 2 item trigger is enabled in the template, send data:

   zabbix_sender -z 127.0.0.1 -s trap -k trap -o 'error.eth3'
   zabbix_sender -z 127.0.0.1 -s trap -k trap -o 'error.eth1'
   zabbix_sender -z 127.0.0.1 -s trap -k trap -o 'error.eth0'
   

   #Try to recover the problems:

   zabbix_sender -z 127.0.0.1 -s trap -k trap2 -o 'recovery.eth1'
   zabbix_sender -z 127.0.0.1 -s trap -k trap2 -o 'recovery.eth3'
   

Result:
Only one issue closed, others left opened.

Expected:
1 item trigger works as expected https://www.zabbix.com/documentation/7.0/en/manual/config/event_correlation/trigger

There is no any notification that it should be same item which can receive different items to match the tag. In a given template example tags are matched correctly.
