SIMILAR SUB-ASSEMBLIES SHARE PARTS

Hello,

I have several simple similar sub-assemblies that have some of the same parts in each, when two or more of these similar subs are brought into a assembly the common parts error out on one.

They disappear and if I close the larger assembly and open each of the smaller sub-assemblies individually they are fine, it is only when brought into a larger assembly.
