RISE - Quiz calculation animation blank with no "Take Again" option

Hello there!

There's a few of our students that reported that they get a blank calculation at the end of the Quiz in some of our RISE lessons. When checking the HTML code under the hood, we can see the code lines for the animation/calculation, but it's not showing in the browser. This problem prevents the lesson from being marked as completed in our LMS.

We tried to replicate the problem on our end and it works fine when we try, but we did receive about a dozen of messages about this from students. We tried to log in as the students and there's no error/warnings in the browser's Console, no error shown either in RISE. We're using SCORM 2004 3rd Edition. It's very difficult to see what's the problem.

Attached are the Quiz settings and an example of what the students are seeing. Do you have an idea what's happening?

Thanks!
