I am working with tax parcel data.  Documents get scanned and can be applicable to multiple parcels.  So I created a template with a field group for all the parcel metadata.  Not all of the fields in the group will have data for each parcel.  Some are null, which is likely causing my problem.  In my workflow when I assign field values sometimes one field will go into a different group than I am assigning at the time.

When I do a track tokens, I can see the correct data for the entire group getting assigned at the same time.  But the end result when viewing the document is wrong.

As an example I have in workflow:

Parcel 1: %(TaxID) = 35147, %(PinNumber) = 07-etc-013100, %(LegacyPin) = null

Parcel 2: %(TaxID) = 658, %(PinNumber) = 07-etc-013000, %(LegacyPin) = 002163504220

End result in the document is:

Parcel 1:  %(TaxID) = 35147, %(PinNumber) = 07-etc-013100, %(LegacyPin) = 002163504220

Parcel 2:  %(TaxID) = 658, %(PinNumber) = 07-etc-013000, %(LegacyPin) = null

Is this working as expected?  I would have assumed a field group would stay together when it gets assigned to a template.  Or do I need to convert all null values to something?  The fields are all multi-value and not required.

Thanks.
