Issue with Xenoblade and 360 controller set up

I encountered a strange problem with Xenoblade using a 360 controller. For some reason, when receiving no input, my character likes to walk to the right. I've tried a number of revisions and get the same results each time. The only other game I've really played around with on Dolphin is Fire Emblem: Path of Radiance and I've not encountered the same problem in that game. It also doesn't happen in any other game I use my 360 controller for (a number of steam games ranging from Dark Souls to Hotline Miami. This is the first time I've had this problem, so I'm fairly certain it's not the controller itself)

I uploaded a short video to youtube to demonstrate the problem (the quality is shit, but the problem is clearly visible)

These are the settings I'm using:



Any help would be much appreciated. I'm very confused.
