I am trying to reorder a grade item (assignment) in a single category with 20 other grade items (all assigments). The "move" fuction (blue icon with arrows) was working fine before and allowed me to move these items as I pleased but then recently stopped allowing me to move the items. I CAN move the items to a different category, but cannot move them around within this category (none of them will move). I created a new assignment and it promptly placed itself at the bottom of the list and will not move within this category.
I duplicated the course and have the same problem on the new course. Any insights into why this is happening and how to fix it?
