Review comments display at end instead of by screen

We are having an issue in which the Review 360 comments from one of our reviewers display after the final screen. When they review it the first time and comment as they go through, the comments display on the correct screens. When they use the Prev button to go back through the course and jump around a bit, the comments all end up displaying after the final screen instead of the screen on which they commented. 

It has happened for them on multiple course reviews. No one else is having the same issue. They have an Articulate account to review, but do not have an Articulate license.

I can't replicate the issue, and my comments are displayed in the correct locations.

Any suggestions would be appreciated.
