Thank you Emma for your reply and sorry for late response. Long weekend labour here in NSW.
The first scenario you raised does not seem to be relevant to my case. The assignments are certainly not set as groups.
But the 2nd scenario I am not sure how to verify if it effects my situation. Are you aware of log file one can check to see what is accumulative effective permissions on per user to see if there is some specific setting in there unintentionally though, causing what I see?
Yes it happens on all assignments for this particular class. What makes it even stranger is that this new class is created restoring from backup of another class which did not have this problem.
