We have the following situation.
There is a template for monitoring various parameters.
This pattern is connected to the host. ITEM-s created with the type of zabbix_agent.
ITEM-list s from host to host different.
For example, we have to test ITEM proc.num [sshd].
Trigger:

<1
And the Item, Trigger and by default have the status Active.

On a host that connects to the template, sshd is not running and its control is not necessary.

As a result, after adding a template to the host for this element is Drawdown of the trigger.
In order that would extinguish the trigger in previous versions of Zabbix just needed to move to a state ITEM Disable (because sshd on the host state control is not necessary in principle).

Now (in Zabbix 1.8.4) after the transfer to state ITEM Disable this item is no longer controlled, but the trigger (after the first initialization when adding template) in Monitoring -> Triggers remains active!
In order to be the trigger was not an active element of the disconnected, it must be translated into the state handles Disable, and then returned to Active.
