OD updated files deployement failure

System

Hi ,
I have setup for workflow in TS 6.7.1 in which the OD of files to prod servers is configured from pre prod server.
Issue is updated files are not getting deployed to prod server with newer version(updates are not getting reflected) and newer files are getting deployed successfully. I have checked logs deployment is successful.

Please advice is there any parameter which needs to be set for OD.

Thanks in advance
Manu
