Data Quality - PO Box in USA Regulatory Address Cleanse

Question

I am working with the USA Regulatory address cleanse and noticed when there is an {PO Box} format in my input, the transform is assigning the {PO Box} as my Primary Address Output. Is there a way for me to assign the to the Primary Address output and the {PO Box} as the Secondary Address output? Or is this how the Address Cleanse parses the data?
i.e.
Input Fields
Multiline1                                          Multiline2
4760 Address Dr                            PO BOX 78
Output Fields (I get)
Primary Address                            Secondary Address
PO BOX 78
Output Fields (I want)
Primary Address                            Secondary Address
4760 Address Dr                            PO BOX 78
Due to Apartment numbers being in either my Multiline1 or Multiline2, I can not use those use the Multiline output columns. Unless there are setting I need to change in order for me to get both scenarios working.
i.e.
Input put fields
Multiline1                              Multiline2
1234 Address Apt.2            
5432 Address                      Apt.3
-Thank you

David,
You specifically mentioned the settings on the client.  But is that path the right path on the machine running your job server? 
My next question is have you downloaded the RDI directories from the USPS?  You must purchase these directories directly from the USPS.  You should have these two files:
rts.hs11 and rts.hs9
Thanks,
Ryan
