SD latest version on IPad / PA Rosetta

Does anyone l know if there is a filter on the traffic displayed / warned by SD? If so how can we access this? We are regularly encountering ADSB traffic that is detected by PA and displayed on the PA “Radar” but not displayed on SD.

Last night whilst on a class D transit an airliner was notified by ATC of “GA traffic 1200 feet directly below” No indication of it on SD, but there it was on the PA radar.

We have the connection set up and SOME traffic is displayed.

Any help would be much appreciated. Thanks Guys.
