MK 9 Question

[KATO]

So I've been playing MK 9 recently for the very first time.......got it for the b-dy from the wife; she got me the Komplete Edition, so I don't have to DL anything, awwww snap.

Anyway, I've been playing the shit out of it, and bought a lot of the 2nd fatalities from the krypt area.......but when I try to memorize them from the fatality tutorial place, it will only let me select their primary fatality.

How the fuck can I practice these things if it won't show up on the move list???

I mean I know I an reference the internet, but I don't wanna have my fucking laptop sitting beside me every time I play the damn game.

stupid basic question I know, but help would be appreciated
