When I choose arrange by assignment group I expect the grades to be in alphabetical order. They are not. Why not?
If you sort by assignment group, they will be sorted in the order those assignments appear in the Assignments or Modules list. You can re-order things either of those places, by dragging and dropping on the left (there's six dots.)
For more clarification, it is sorting like this:
LD1...LD20, LA1...LA20, HM1...hm16, HMsumry, XC1...XC10, LP1...LP5, AK1...AK5, CourseInfoQ, SylQ, LJ1...LJ5, LQ1...LQ17, XM1...XM5.
