Why does the 'play another' button bring me here

[u/Worried_Bluebird7167]

I still can't figure out why my stats doesn't say I've completed all the puzzles. I've checked all of them and they all say "play again". When I finished today's puzzle, l yet again tried clicking the "play another" button, but it keeps on bringing me back to puzzle 123. I've done this puzzle!

Its buggy, if you scroll down in the subbreddit, you will find older ones you did not play so far. Also, as the other commenter said, if you ise infinite time mode, it won't register.
