Tcp Request return msg.payload

The TCP request returning with two msg.payload, MEAN, with single reply from server socket this TCP request client return back with two msg.payload. Please check below image and let me know how to fix?
For your information: sometime TCP request returning with single msg.payload just like I want it but not for long.

In the config of the tcp request node there are different options for when the Node passes on what it has received.

What have you got set for the "return" option? Have you tried changing it?

return option I set to : never- KEEP CONNECTION OPEN...
Now I already solve the problem by using join Node.
