Using CodeRoad and coderoad not able to reset

So I’m intrigued to begin to learn Bash. the first course in the relational database stream. All is going well…following along with course.
Problem is that at some point I did not enter the correct answer then tried to reset. the issue is that even if I do put in correct answer, The answer is not approved seemly the system does nothing. So I go back and try to restart where I left of by going into the dashboard and starting the lesson again. same issue. Can I do an occasional save to restart from, and not have to relie on the system in case it breaks causing me to start from beginning. ?
