Adding a rubric to an assignment that uses Outcomes

Linda.B.584

I have added Learning Outcomes to a course and have connected different outcomes to different assignments. Each of the assignments has a rubric however I can't attach the rubric (greyed out). I disabled the Competencies tool as directed in order to use the Learning Outcomes tool, however now I am reading that in order to attach the rubrics I have to enable the Competencies tool. Not sure what to do. Has anyone else had this issue?
