When you say "targets", do you mean traffic?
Just in case, can you check your "Map Mode" and make sure you have "Traffic" layer enabled? Otherwise, traffic won't show.

Otherwise, the best way I can debug this is to get two ADSB logs from you, from devices running side-by-side, one which shows the traffic , and the other which does not. To generate these logs, just do this:
1. Menu=> About => Connected Devices => Wireless Device => Enable ADSB Log
2. then fly...
3. After landing, restart iFly, and on startup, answer "no" to keeping Adsb Logger enabled, ELSE it'll overwrite your adsb log files (note, for 9.7, I have a fix for that).
4. Then when online, do "Menu => About => Send Bug Report => Select Log => select "AdsbRaw.bin" file
Do that for both devices, and from the logs, I'll be able to see what's going on.
