It looks like there is an issue in the multi-outcome scoring editor, on the weights tab.
The text for displaying the % each category contributes to overall score (each assignment when the category is expanded) is white... and the background is white, making the % invisible. When hovering over the row, the row becomes light grey which makes the %s just barely visible.
Wish I could attach a screenshot... please let me know if need to provide more guidance to see what I am referring to.
Maybe a setting on my end?
