Data Shuttle not updating a field from the source file to my Smartsheet


I recently added a new field to my data extract and data shuttle populates that record in my Smartsheet, but when that field value is changed on my extract data shuttle is not updating that field. I am not sure if it is only happening when the field is a certain value. The only way I have been able to fix it is by deleting the record from my Smartsheet. When I do that and rerun Data Shuttle it populates correctly.
