I had a similar issue, my PC gamepad wasn't mapped the correct way,
and since I had to change it in the game option, the icon from this mod wasn't the right one.
(when I push the equivalent of "X" on my gamepad, the game said I was pushing Triangle etc...)
and I didn't want to use gamepad mapper, they all crash on my (clean) computer, anyway,
since I work with photoshop I tried to mod the mod's png, and it worked.
here the PSD (photoshop format) with some layers for the X, O, Square, triangle button.
you can make more if you want.

I made a video if that could help, but since I'm not really good at talking english I didn't spoke in it.
