Having a recurring issue when building rubrics. I've been building out the rubric rows left to right. Every once in a while, the cell in the last column to the right is missing the editing pencil icon, and I am unable to add any content to that cell. This happens sporadically. I cannot find a workaround other than to scrap the rubric and start over. Has anyone experienced this glitch, and do you know of a workaround? Thanks.
