What to do if past project progress doesn't save?

I’m nearing the end of my Responsive Web Design certification and it appears that both of my Ferris Wheel/Penguin projects are reset to 0% completion. Is this a known bug and is there a way to restore or should I go back through them?

i don’t know why you are not seeing your program, so long as you are logged in you should have your progress saved. In any case, you can ignore this as it doesn’t affect your ability to get a certificate. I wouldn’t waste time redoing anything.
