Trigger to Show Base Layer

This may be a related issue. I have a matching drag and drop interaction that allows 2 attempts, and I have created custom Correct, Incorrect, and Try Again layers. I set the option on the base layer to reset to initial state when revisited.

I put a Continue button on the Try Again layer that I want to take the learner back to the base layer of the same slide, but I can't get it to work. I would swear I have done this in the past -- but maybe it wasn't for a quiz slide.

In the attached Storyline 1 file, Slide 1 shows the built-in layers, and Slide 2 is the one I customized. The only difference I can see between the setup of the two slides is that I added an "answer" layer which has the triggers that would have been on the Incorrect layer.

In my full course, I tried having that Continue button jump to a different slide, and that worked. So, why won't it jump to the same slide?
