Cocos studio along with c++

I am trying to get the multires stuff sorted out in cocos 2dx.

I followed the steps described in this post: Multi resolution Support for Cocos Studio 2 problem solved! :D

I create a scene with a design resolution of 960x640 This works pretty well as usual but let’s say I choose 854x480 to test the app.

It seems everything is stuck to the left and there’s a large black border along the right hand side.

You can see the first picture everything is fine, the design resolution and the screen rectangle are the same.

In this second image the screen size is set to 854x480 and you can see the background is now only on the left side, there are two empty sprite nodes which were off the design area in cocos studio but they show up here.

How do I make sure that everything stays the same when the device window is different than my design resolution? If anything I would like to prevent stretching but at least keep everything centered in the screen.
