The successful completion of one problem marked a different problem as completed

I was attempting the problem 15 of the DP-Greedy pack. I made 2 unsuccessful submissions and then tried problem 16. The problem 15 was showing in progress as it should. After successful submission of problem 16, problem 15 got marked as completed and hints for problem 15 were unlocked and I was able to view the debrief of 15, whereas I didn’t even complete problem 15. I then resubmitted my solution for problem 16 and now the debrief for the same got unlocked. It actually should show that all are completed except 15 which should be in progress, but it shows all problems completed.
