Hi, Xinya;
I've made the changes you listed and have just about lost my mind waiting for the Historical List to update to 24 dramas...haha! I'm waiting to add the Crowned Clown...and waiting, and waiting (lol)
Seriously, it has taken about 40 minutes to add 6 titles. Apparently, the lists update "approximately every 5 minutes", but sometimes the update takes longer.

It seems like some dramas are missing from the Historical Drama list. For example, Moon Lovers and the Crowned Clown were in the top 25 in round 1, but don't seem to be on the round 2 list.
I also think The King's Affection and Love in the Moonlight belong in the Period Drama category.
