blockMesh/paraview cutout view
 

When I make a mesh using blockMesh and do a slice in paraView, it seems to show the blocks as being sliced though the middle instead of being one block all the way throughout. Here is a screenshot:

This is a cut from the example cavity tutorial, which is a 2D problem. Are these cuts actually here? or is it just a view setting I have messed up. Any help would be great.
