Linux Fundamentals - Unable to Take Course Again

Course: Linux Fundamentals
Question: I completed Linux Fundamentals a bit ago but wanted to go through the course again while I wait on another issue with Elastic Labs to be resolved ( URL launches to Setup instead of Kibana ); however, when I get to the lab portion of Linux Fundamentals it says the Lab has been Completed. Is there any way to reset the environment so I can go back through and refresh myself on the concepts now that I have a bit better grasp?
