State on a single flip card won't change to visited

The built-in states can produce unexpected results if you create a trigger that that repeats their built-in action. In terms of action they are reliable.

I downloaded the /story from your original post. I found nothing wrong with card 3.1. however, layer Card 6, unique among the layers, is not set to hide other layers.  See the attached video to see Card 3.1 change to the visited state.
