Xpadder + 360 controller works accept for one button

[NNUBBERNAUT]

I have a Hyperspin setup, so I'm particular about what keyboard buttons I have mapped to my 360 controller using xpadder because of multiple emulators and trying to seamlessly transition between them.

Everything seamed to have been going well accept for the keyboard button I used for "Y".

I mapped "T" on my keyboard to be the "Y" button of a snes gamepad, but its not working. Any ideas why?

Every other button I mapped works great. I'm deeply annoyed by this.
