Doing a little mistake in DC. :\

[Deep]

Hi, I am having a problem with DC.
I am doing very little mistake in DC but can't figure it out. :/

So, I changed Freeze's ball and column's effect to fire effect. (effect 3 to 2).
And, in the game, when the ball hit the opponent, he burns in fire, is flying in air bit isn't dropping on ground.
What mistake am I doing?



And one more help, how to change whirlwind's effect to fire effect, I can't understand the tutorial on the site.
