Incorrect PID detected by PE / OpenPorts

Hello,
I was evaluating PE and I have the following problem:

I have a tcp server which does a fork-on-accept when a new connection is established by a client. The socket is inherited by a worker process which handles the client requests.

I ran OpenPorts while there were two client connections established and two worker processes served them.

The tool detected the local ip and ports and the remote ips and ports correctly but it associated both connections with a single worker PID (it should have associated a worker pid per each client connection).

is there a solution to this behavior? I want to distinguish which worker process serves which client.

thanks in advance!.
