Halfway through Bootstrap sec., all challenges already completed

Greetings, fellow coders! I have found kinda bug, I think. Recently, I’ve wiped all of my little progress made on FCC in order to start it all from scratch. And today, being halfway through Bootstrap section, I realized that all the code that I supposed to type is already there, all I need is to hit “Ctrl + Enter” and go to the next challenge where this pattern repeats. What’s the deal with that? Thank you in advance

What do you mean by “wiping all of your little progress”?

You know, in your profile settings you can delete all your progress and, to be exact, you can delete your whole profile. And this radically wipes all your progress made - completed challenges and other things

Thank you, this really helped!
