Uploading using the migration tool does not work when the Address field is unique

Uploading using the migration tool does not work when the Address field is unique

I have a spreadsheet that I would like to upload to Zoho Creator to update records when the address field matches. I tried using the migration tool many times, but continue to get errors. For some reason, the decision box fields are not updating This problem was first reported to Zoho Creator support over a month ago, on May 8th. The support team has promised a quick solution many times, but has not provided one and does not have a timeline for when this problem will be solved. 

Please advise! Thank you.
