I tried the workaround.  You must complete each field.  I made up a middle initial and put an x in the second address line & saved it.  Then when I went to remove the middle initial & the x, it wouldn't save.  The solution was to go to those fields again and put in three space bars which effectively removed the made up incorrect information and acted like there was still an entry.

Not the fix I was looking for, but the outcome worked.  It still should be fixed by the techs.
