"Use O as confirmation button" cause unavailable cancel button "X"

[RADAC]

In ppsspp menu, if i set "Use O as confirmation button",
- O and X both button will become confirmation button in ppsspp menu.
- I cannot use X button as cancel button.

for example, focused "Save state"
   
In this case O and X will be save, X button dose not work as cancel button.
So it will save though not intended.

There are similar situations in "Settings" screens.

thank you.
