Add Field error moves existing field data around.

I am trying to add a field to a shapefile. Whenever I do it will move all my exisiting data around and add data to some fields. I have attached a before and after picture. This happens if I add the field manually or with python  arcpy.AddField_management  This only happens on shapefiles that have the same data structure as this one. The other shapefiles that come from the same GPS unit do not do this. Any ideas?


update the field data also moves around if I delete a field.
