Delta Live Tables has duplicates created by multiple workers

Hello, I am working with Delta Live Tables, I am trying to create a DLT from a combination of Dataframes from a 'for loop' which are unioned and then DLT is created over the Unioned Dataframe. However I noticed that the delta table has duplciates. And the Number of Duplicates per Unique Row is the number of workers in the Pool Cluster. How can I avoid this duplication from happening.
