Adding DFF values to Asset in Mass Additions

I am obviously missing a step here somewhere.  We are on 12.1.3 and I am testing adding assets via Web ADI with DFF values.  I have:

1.  Defined DFF segment on Application-Assets Title-Mass Additions

2.  Entered the data in my spreadsheet

3.  Uploaded the data successfully

4.  When I look at the asset in Prepare Mass Additions, I see the DFF information

5.  I run Post mass additions

6.  When I look at the asset in Asset Workbench, I don't find the DFF information anywhere on the asset

Does this info not transfer to the asset in the post process?
