How to make a trigger stay?

So I have a set of triggers on a "latch" setting.

When I position the timeline into a certain frame I press the assigned key to the trigger and it shows up, but as soon as I advanced the time line to the next frame the trigger disappears. 

How can I make the trigger stay?  and then make it go away as I press the key again instead of disappearing on its on?   I already have it as "latch" trigger.
