Cocos2d-X V-3.6, WP8.1 Resources duplication issue in VisualStudio 2013

I have added "hd" and "sd" graphics support in my game, it works fine on Android and IOS, but when i build it for WP8.1, it gives the following error:

Error 14 error APPX1101: Payload contains two or more files with the same destination path 'test_image.png'. Source files:

D:\Cocos2d-x\MyGame\Resources\hd\test_image.png

D:\Cocos2d-x\MyGame\Resources\sd\test_image.png

If I add only a single file i.e either its in "sd" or "hd" directory, it runs fine. but i need both to support various screen sizes
