Finale combo not working (solved)

It's just as the title says. It won't work.
This is my finale combo : impact > finale (smite) > blizzard (smite)
I have 2k mp, which means it is more than enough, i only need 10 bars after all.
The strange thing is, it works fine last time. But i test it again the other day and it just won't activate no matter what i did. I even didn't change any of my equips

 

Maybe your more than 13m away from enemy?
Finale only activates <13m

Also, make sure Famillia is active

 

It still didn't work even when I'm 1m away . I tried activating familia first and it actually worked tyy!! But the strange thing is, i used this yesterday (multiple times) without activating familia first and it was still casted. That's what making me confused. Thank you btw!!
