Need Assistance With MySQL Migrator

I am working on migrating a 7.7 schema MySQL DB to PostgreSQL. After executing:
./mysql-migrator -source source.properties -target target.properties

I got the following error:

Duplicate pop values detected in projects table. Please clean the table first. Aborting migration.

Has anyone run into this issue before?
