batchnode cropping sprites

I’m positioning many sprites in a CCSpriteBatchNode but the positioning is weird. Here is an image of the result

The two individual sprites looks like this:

This is the code that i use to initialize the batch node

CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("batch.plist");
batch = CCSpriteBatchNode::create("batch.png");

does anybody know what is going on?
