The manual page: https://www.zabbix.com/documentation/3.0/manual/web_interface/frontend_sections/configuration/hosts/triggers

Say about the defaul value of trigger filter:
"A list of existing triggers is displayed. By default, only the enabled triggers are displayed. To display disabled triggers as well, use the Show disabled triggers link to the right in the Triggers bar."

But this is not true. The default value is show all triggers.

I try with last version o Zabbix available today. Build (57353)
