Computation Layer not working on student screens

Hi. I have created 3 activities where students can check the matching as well as have fireworks go off when they are all correct. On ‘student preview’ it works, but when my students went in, they do not have that slide at all. Here are the activities. I made them public in case you need access. PLEASE help me with this as I took awhile to do it and now in class it isn’t working… thank you!

I’m unable to replicate the problem. When I tested your first card sort, both using the Student Preview and by making a dashboard and logging in as a student, the fireworks slide worked both times.
