We've noticed some surveys from last year appear to be displaying notifications to students if they haven't completed it, even though it's been several months since the end of term. Here's an example from student 340001379, an Audit student in class AS4120 Spring 2019-2020 (last year). The other class, AS4010 is a current one and is correctly displayed.
I've checked the Term information, and it has correct End of Term and Add/Drop dates, so I don't think that's the issue.
Not a huge issue, but I thought I'd flag it.
