Layer trigger not working in scene or entire project preview

I am having a similar problem to that described above.  I created a drag and drop slide.  When the two correct slides are dropped onto the correct targets, the "Correct" layer should appear, otherwise, the "Incorrect" layer should appear. (For ease of debugging, the graphs are tinted red when incorrect and green when correct.)  When I preview the slide, everything works as intended.  However, when I preview the scene or project, the submit button automatically advances to the next slide, regardless of whether the answer is correct or incorrect. The "incorrect" and "correct" layers are skipped entirely.  I have attached a simplified two slide example to demonstrates the problem (and I have verified that the issue persists after the slides have been published).  I appreciate any assistance.
