Change Data Capture SSIS not picking changes

I am trying to implement change data capture in SQL Server 2012. I enabled it at database and table level. when i try to update the table, CDC_CT captures the changes. However when i am using SSIS CDC components, it doesnt pick anything. the version of SQL server is: Microsoft SQL Server 2012 (SP3-CU10-GDR) (KB4057121) - 11.0.6615.2 (X64) Jan 9 2018 21:26:48 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.3 (Build 9600: ) (Hypervisor) Can someone please guide?
