[DU] Final Exams not ticking off

I have two Sims at University. Each had one final exam. On last day of term  “Final exam is in an hour” notification came up for both, both attended class and, when in class, “cheat on exam” came up as an option. One even got an uncomfortable moodlet in relation to the exam, but after this class, “Final Exam” was not checked off for either sim. I have seasons installed, but neither sims missed any classes because of holidays and there was no holiday on the last day of term. I thought this issue was supposed to be fixed so am pretty disappointed.
