Halloween Spirit Quest.

According to Halloween Spirit Quest, we have to put 8 walls, 2 catholic candles, 4 Tables. I put 2 catholic candles, and four tables in my diner, which showed in the quest as completed. But to my utter surprise, when i place 8 new walls Creepy Crypt, it did not show in the quest to be completed. Kindly look into the matter and advise me. I again replaced these Creepy Crypt walls with the old walls.
