Choices not read aloud on smart display, read as "object object on smart speaker and action fails

[alee67]

After finding some problems migrating my currently deployed Trivia Quiz template based action to the Actions Builder platform, I simply replaced my sheet in config.js with the sample sheet on the original template page, which has categories and difficulty levels, and the English sample sheet in the documentation here, which doesn't have categories or skill levels and found the same problems.

On a smart display, the choices for categories, skill levels, and answers to questions are displayed on the screen, but none of the choices aren't read aloud. The original template read aloud all of these choices. Aside from this, everything seems to play correctly.

On a smart speaker, the choices are all read as "object object", and action has trouble accepting responses. The sample without categories or difficulty levels quickly fails, while the sample with categories and difficulty levels fails after choosing a category and difficulty level.
