I'm confused What "lines" are you looking for ? If you want to use multicast then you have enter a multicast address in WSJT-X.
Unicast still works just fine (127.0.0.1) if you have no need for multicast (I don't). Uncheck the option for multicast in JTAlert.
I am using JTDX 2.3.0, JTAlert 2.16.17 and HRD.
