Please do the triggerscope to confirm, but I suspect that will be it.  If it was a GTR plug-in that would be no problem as there is an on-board jumper to swap trig 1/2, but no such feature on the 300Z plug-in.  If you do the triggerscope and notice the waveform is showing on trigger 2 and trigger 1 is just a flat line, then you will have to move that pin.
