Hmm, email me the template at Dominic@HomeInspectorPro.com
and I can look at it. Must be something up with the beta. You said that you deleted the template and started over, I'm guessing you actually never closed the program so you still had the same template open, otherwise I don't see why you would have gotten the duplicates.
I have an idea on what could be causing this, I'll check it out. Send me your template (.tpz file in the Data folder).
