Heatmap not working on my profile

Minor issue, but 'id like to see the green squares to see my progress easier. is this a known issue, is there anything i can do to fix it, or just wait for a fix?

The heatmap is broken and needs tobe replaced. I don’t know if it is currently being worked or what progress has been made. If you would like to join the community of contributors, you can start by checking out the contributing documentation on FCC’s GitHub.
