Freecodecamp have deleted all my completed challenges?

Yesterday i completed all challenges from begin to half of Basic Javascript (like 169 challenges).
Today i dont have these completed. Calendar in my profile seems doesnt work, it shows me that i didnt complete any challenges.
Why is that?
Is this because i havent sign with GitHub profile?

Edited: Now i see code have saved, but i have to “ctrl+enter” all challenges. :confused:
