"mark all as present" marks all students as absent

• [X] I have already searched the Issues page, and I am sure this bug report isn’t a duplicate.

What happened?

Selecting the "mark all as present" option during assembly causes all students to be marked as absent instead, so far this only happened to just one class (m405/2024). Admins in the class are unaffected for some reason 😉.

No particular steps to reproduce.

Steps to reproduce

1. Mark all students as present during assembly
2. If everyone is marked absent then you've found the issue

I perhaps did not find the issue, for now. (Could not replicate)
