Duplicate items in cut-list

I'm new to cut lists and I'm having a problem.  I have inserted a cut-list table in my drawing.  Several of the bodies are duplicated and I can't figure out how to fix it.  There is another case of six instances of the same body showing up as 4 in one folder and 2 in the other.  I can't post the part because of proprietary issues.
