I am a TA for a course and grade assignments submitted by students. Recently, many of them have loaded blank when I go to grade them. Each time the assignment name is separated by % signs (like this, "week%10%reading%). I thought it was just the students submitting it, but a TA in another course says that they are having the same issue. Is there anything I can do to fix it so they don't have to resubmit it and I have to grade it all over again?
