Trigger sends more than 1 notification per incident

[YakovF]

Hi!

Could you please help me?

I have
1) Zabbix 2.4.8
2) Configured trigger - https://yadi.sk/i/lgrn4l5e389kgN
3) The problem is if one of the subrules will be triggered I'll receive 3 notifications (which is equal to number of subrules in this rule)
Based on documentation it doesn't look like this behaviour is correct.

Could you please tell me how I can fix it?

Thx.
