I found couple of old threads about this issue, but they seem to indicate that the problem has been fixed, but it doesn't seem like it has.
I created a rubric through outcomes. This rubric would be used for all the discussions in the course. I saved the rubric, then edited it, then clicked "use rubric for grading," saved and closed. Then I searched for and applied that rubric to all my discussions.
When I went to grade, I found the grade wasn't transferring. I edited the rubric from that particular discussion and realized the box was no longer checked.
What's the work around? Do I need to go into each assignment and make sure the box is checked? In other words, can I not check it at the rubric level but at the assignment level? Also, will I need to recheck this box every time the course is copied?
These are the two threads on the topic that I discovered, but they're from 2015 and 2016. The latter indicates that the issue was fixed.
