I made a very simple example of smiley moving in selected direction. The direction is set in a variable (1-up, 2-down, 3-left, 4-right) and the condition is set on a trigger "timeline starts" of this object (smiley). This allows to copy this objects with the triggers, but unfortunately doesn't work.
At the second page I change "timeline starts" trigger to slide and everything works as expected. Anyway, triggers won't copy when set that way.
Is this a bug? IMO both slides should behave the same (smiley should go up).
