try locking on to the enemy first and then charge up to max power finally press
R-2+Up+triangle.

it may be you have a different controller setting or you're not locked on. Press L1 to
lock on to your opponent and then hold L2 to charge your ki. After you have enough, press
L2 and either up and triangle or just triangle (***uming your using the default controller
settings). If you charge up to max power, you can then use your super finishing move which
is L2 down and triangle, and if none of this works and your using the default controller
settings, then it's a bug. Hope i helped.
