Any questions that teachers have to manually grade (essay, short answer) are automatically calculated as zeros in Quizzes.Next. There are 2 major issues with this:
1. Student's grades are completely inaccurate until the teacher grades them. This can cause serious issues like suspension from a sports team due to grades, consequences at home, and unneeded anxiety and stress. Yes, I can mute the assignment so they don't see that grade at home, but administrators who are determining eligibility see it as part of the average.
2. Because Quizzes.Next considers this question already graded, as a teacher, I have no way of telling which responses I have graded and which I have not. In the old Quiz system, it shows a document symbol in the gradebook and a little orange dot next to their name in Speedgrader to show that these questions still need to be graded. When you are look at a specific student's quiz in Speed grader, it tells you what still needs to be graded, but still shows a check next to their name in the list, so you have to scroll through every student to see if it has been graded. With hundreds of students turning in assignments at different times this is not helpful.
Considering the old version has this, this is something that should have been fixed before it ever came out of Beta. It is a serious glitch in how Quizzes.Next interacts with the Canvas Gradebook.
