Duplicate Component Names in CW Lib. - which one does it use?

I'm showing more than on version of a component in the Circuitworks Library, and each has a different part associated with it.  Which one does Circuitworks use, and how/why?  If you look at the picture attached, you will see I have 5 components called SO8.  I didn't think it would allow you to have more than 1 comp. with the same name.
