The value that you have identified “-5=-4320204&_dc=1409133759798&aftk-5=-4320204” for correlation is incorrect because it is not coming in any request’s response, if you go to generation log (that you have attached) and search this value then we see.
So problem is not with this values there is some other values which need to correlation, if possible share your whole script, generation log and replay log with advance trace enable.
