Steps to reproduce:
Create items with multiple parameters in the item key
Example:

net.dns[8.8.8.8,example.zabbix.com,A]

Create calculated item with aggregation and specify wildcard in the item key

This will not work:

sum(last_foreach(/host/net.dns[*]))

This will work:

sum(last_foreach(/host/net.dns[*,*,*]))

Expected:

Wildcard in the item key matches all arguments.
Otherwise, this should be documented with examples.
