Hello!

This all is great content! It isn't showing up in any of my skill breakdown sections. All the grades I had mastered still say mastered, although if I go to the "Practice" tab under say 8th grade the stars are grey, showing I haven't begun these exercises, but there are no grey squares in my skill breakdown. I'm assuming this shouldn't be this way, but that is what is happening in my account.
