Datamart showing wrong binary value

Hi guys, I have one of the weirdest issues. I am trying to connect the dataflow with my Salesforce and then datamart connected with dataflow: Salesforce -> dataflow -> datamart.

The actual value of the Active__c column in Salesforce is FALSE against a record. The value in the same column against same record in dataflow also matches with Salesforce i.e. FALSE. However, whenever I try to connect Datamart with Dataflow, the datamart will show TRUE for some reasons. No matter how many times I refresh dataflow or datamart, or create a new datamart, the value in datamart always remains TRUE. How do I solve this?
