Challenges are not working

[Yuweien]

Hi,
My name is Yuwei Wang from the ToMCAT project. My colleague of the team Selena @SalenaAshton and I found that the 'Extract' button of the Challenges does not work. We are using the latest version of the repo, but I had an older version of this repo on another computer, and that one can successfully print the labels and dependencies when hitting the Extract button.
Thank you for reviewing this issue.
