Retroarch Gamecube Controller Issue

[sipes760]

I am having a real big problem playing Gamecube games using Retroarch. The sound, video, and framerate is great. The problem is with the controls,  The left stick on my X-Box 360 controller is controlling the analog stick and the digital pad at the same time like they're mapped to the same thing on the controller. For example when playing Windwaker and I push right on the left stick link moves right like he is supposed to, but it also brings up the map at the same time, and you should only be able to bring up the map by pressing right on the digital pad. I checked the controls in the Retroarch menu and no buttons or directions are sharing the same settings, so that is not the problem. Any help with this would be greatly apprciated.
