Dualshock 4 Left Stick Not Working on 5.0-15680 Version

[BladeGuy9]

I downloaded a Pokemon Colosseum ROM Hack and my character doesn't move down. He just moves up whenever I hold down on the left control stick. The D-Pad down direction doesn't even work. I have no idea what to do to fix this. I have the latest dev version of Dolphin, so I know it's up to date. Thing is, this issue doesn't happen with the 4.0 version of Dolphin, but I wanna play on the new version to speed the emulation up at certain points.

Any help would be greatly appreciated, please and thank you.

In Dolphin's controller mapping window, calibrate the left stick.
