Content Payload Search in SAP PI 7.1 EHP1

Hi Experts,

               I am trying to implement content based payload search in SAP PI 7.1, I have set two filter criteria one for IDoc and other for proxy, For Idoc filter criteria is working fine but incase of proxy it is not working at all.

Search criteria for Idoc:

Idoc Filter criteria working successfully.

But when I try and set the same filter criteria for Proxy message it just doesn't work.

Filter criteria not working.

Please suggest me as to what is it that I am missing in these proxy configuration.

Also, I have went through certain threads which states that these filter criteria don't work in SAP PI 7.1 production server, Please provide inputs on the same.
