Jerry,
Can you look and see what Software Version you are running? Menu, About, Version and Contact. Make sure you have the 7.6.7 version. In an earlier version we were not showing the traffic outside of your "Alert Area", but people wanted to see everything, so it was added.
I've tested the ADS-B In and In/Out scenario and they show the same traffic, provided the TIS-B has been activated by the Transciever. If you are using ADSB Out, then you should be seeing it all. I suspect you may be running an older software version. Keep us posted as to your software version.
