@elinor_wren -
I agree. There was another question on the forum a few days ago dealing with this issue as well. I don't remember the title of it, but in it I made the comment that it would be nice if a dialog box would come up stating that the two point values were different. And then give you the option to make them the same - either use the question point totals for the quiz total or use the point total for the quiz distributed between the questions(in some manner), or at leave them different. This is done with rubrics on assignments, so the thought process is already present in Canvas - I just don't know how that corresponds to doing the same thing with New Quizzes.
