Rubrics for Raw Score Assessment

[ndockter]

Hello,

I created a raw score assessment in Mastery Connect. I added the assessment, clicked "create new," and chose "raw score" as the source.

I added the assessment to the correct module in the class. After inputting essential information for students, I saved the page. 

I would like to add a rubric, but when I click the +Rubric button, it disappears and nothing populates. Is this a glitch or can I not add a rubric to the assessment?

Thank you for your help!
