I setup actions/conditions to send mails with the following rule :
#1
Template = Template_XXXX
Trigger value = PROBLEM
Send message to user groups: GroupA

And also I setup following rule :
#2
Template <> Template_XXXX
Trigger value = PROBLEM
Send message to user groups: GroupB

I am expecting to send #1 mail to GroupA to match Template_XXXX.
And to send #2 mail to GroupB to be not match Template_XXXX.

But zabbix-server does not work as my expectation.
It send mail to reverse both GroupA and GroupB.

Is it a bug? or am I misunderstood concerning this configuration?
