2.) As I mentioned, I’m using Kids 4 figures, but also using P5 Will/Penny, and P7 Ben/Kate. Even though I changed Ben’s name to "SW Ben" when I saved the figure, the newly named figure it still shows up as just “Ben” in the preview dropdown. Likewise, Will and Penny have always shown up as just “Figure 1” even when renamed, and even though I renamed the Kids4 figures to just “K4”, they still show up as “The Kids 4”. Haven’t figured out why the new name doesn’t show up, maybe a setting?  

Saving a figure (or figures) to library does not change their name(s).  That name is only name of new CR2.

To change name of a figure, select it and select "Body" as part.  Go to library pallette and under "Properties" tab change entry "Name:" to whatever you need.
