Rise slide does not report anything useful to LMS using xAPI

I have a Rise course embedded in my LMS (Learnupon) using xAPI.  I have a slide in this course that has a button stack with 10 buttons (labelled 1 to 10) that allows the user to rate the course by selecting one of these buttons, and I place this slide as the very last slide after the final exam.  Since this slide is the final slide, the destination of each of the buttons is to exit the course.

I run the course in the LMS and it behaves properly, but I can see only one statement being logged in my LMS (see below), but it doesn't contain anything useful like which button was clicked.  Is there any way to get the system to send more information about what the user did to the LMS?

Thank you.
