I figured out that I need to add the translations to get the nodes to output correctly.

Sorry, I should have answered it earlier. I thought it was a real bug for which I have no time to fix it right now.

YEAP translation is described by so called simple directed translation. It is enough to represent a parse tree but have some constraints. Only one abstract node can represent a rule in a parsing tree. For example, you can write

expr = '-' expr # neg (2)

but you can not write

expr = '-' expr # minus (zero 2)

Using sub-tree in the translation is on my very old TODO list for YAEP. But I don't think it will be actually implemented.
