It would also be good to grab a screen shot of your Traffic page so we can see what you are seeing that causes you to say "I didn't get any traffic input".
This is from my Aera 760 connected to a GDL 52R inside my plane, but my G3X Touch (which is currently using the GNX 375 provided traffic/weather) has a similar traffic page. The top left of the traffic page shows the traffic source which is being used (GDL ADS-B in this example).
You should disable TIS-A traffic on your GTX 23ES configuration. Your GDL 50 ADS-B traffic blows it away.
