Zabbix timer process evaluate same item triggers per 30 sec even if a trigger including "nodata()" is disabled.

I have following item and triggers.

• "Host uptime(in sec)" item updated every 3000 sec (see zbx_05.png)
• "nodata trigger" with "Normal + multiple PROBLEM events" (see zbx_04.png)
• "error occurs with nodata trigger" with "Normal + multiple PROBLEM events" (see zbx_03.png)

I think only if "nodata trigger" is enabled, "nodata trigger" and "error occurs with nodata trigger" should be reported. (see zbx_01.png)
But, even if "nodata trigger" is disabled, "error occurs with nodata trigger" is still reported. (see zbx_02.png)

The following SQL in "process_time_functions()" executed by timer process dosen't check if triggers are enable or disable.
