Please see the attached pic.  Everything you see that has a qty of -, should not be there.  I thought about hiding those lines, but as you can see from the bubbles, that is the number it is using to bubble the parts.  I do not understand why it is pulling in these odd lines.

These are all sheet metal parts.  Items 2 and 3 are sub assemblies, consisting of sheet metal parts.

Anyone know what is causing this?

Thanks in advance.
