Issue when baking overlapped texture sets.

I have a model that when I bake the texture set underneath is having problems.  I need to have my texture set separate so that I can reference it in Unity.  The model was done in ZBrush.  I have many other models that will have this same issue, so I need to figure out for one model first.

Kindly advise. 

Here is the view with the overlap:

Here is what the map looks like for the texture set.  The repeated sections above are quite odd.
