Is that all in one single command block? I'm unsure if you can have two commands entered into one block. Possibly, but I'm not sure.
As for the region overlap, I had this problem before. Simple fix. Simply clone your region you want from its origin to a few blocks farther away, maybe 10, maybe 20, depends on the size. Now destroy the original and use the cloned one as the new origin for cloning. It's the same as the other and no longer in the way.

Hope this helps.
