I opened the console during a session and later played 34 hands of blackjack, which caused the Double Down achievement (play 10 hands of blackjack) to not pop.
I know I can use ModPCMiscStat "Blackjack Games Played" -34, save, exit the game to desktop, reload.
However, in playing more hands, the achievement still hasn't shown up.
I believe this is because the double down challenge (found in the list of challenges in the pip boy) is still completed after doing the ModPCMiscStat command.
Is there a console command to reset the challenge marker?

According to one of the answers to this questions opening console at all makes achievements unachievable entirely. You'll probably need to load a save from before you opened the console in the first place, and then play the 34 hands of blackjack again.
