SmartForms002 Error when activating uploaded form

Question

When I create a smartform with an address element in our pre-dev env, download it and then upload it into our Dev environments, it syntax checks fine but I get a SmartForms002 Error ... Internal Error (Illegal structure of data storage).   It is fine in our pre-dev environment.  I have figured out it only happens when I have an address element and it happens even when downloading/uploading forms within the same env.  We are running SAP ECC 5.0, Basis Support Pack 13.  I have included the steps below to re-create this problem.  Does anyone have any ideas?
- enter transaction smartforms
- type zqmjunk55 as smartform name and click on the create button
- click on Page 1, Right Click, select create and address
- put 60000353 in as the address #, click save and local object, activate form
- click on page 1, right click, select create and Page
- Expand Page 1, right click on main window, select copy
- click on Page 2, right click and select paste
- activate form
- click on utilites, download form and save form on C:\ drive
- click back arrow to go back to initial smartforms screen
- type zqmjunk5 as smartform name and click on utilities, upload form, click green check mark on create form prompt
- select zqmjunk55.xml file you had previously downloaded and click on open, click on local object
- click on change button and then activate form -- error occurs here

Syntax Check and activation of the original form that I downloaded (zqmjunk55) was totally fine.
Syntax Check of uploaded form (zqmjunk5) was fine, just got error on activation.
Address # "60000353" is also fine ... in other examples i have tried i do pass it as a variable and both cause the same problem.
Form interface, import and export parameters etc. are all identical in both forms zqmjunk55 which works and zqmjunk5 which does not. 
If I delete the address window in zqmjunk5 and then re-create it then it works just fine.  In real life though in my real smartform (not the example one) this would not be realistic to do as we would need to re-build our addresses everytime there is a change to the form and we need to move it through our environments. 
It seems to me that there is a problem with the download/upload utility.  I have previously logged a call with SAP, but so far they have been no help so I thought I would try here just in case anyone else has had the same problem.
