Thank you for your post.
I am able to duplicate the problem using City="Santa Clara" and State="CA" and all others blank. My results were:
Home Address _City_ = "Santa Clara"
Home Address_Street_ = "Santa Clara, CA"
Home Address _State_ = "CA"
Home Address _Zip_ = "Santa Clara, CA"
Home Address _Country_ = "Santa Clara, CA"
I have forwarded your entire post to our Development and Software Quality Assurance (Testing) departments so they can change this in a future release.
