[DG11] Axiom Pro mods show own boat as target

We have two Axiom Pro MFDs and since applying a recent software update we now see our own boat as an AIS target which never happened previously. Our AIS transponder is a Vesper Marine 8000 and we have made no changes to that recently. The transponder is connected over the nmea2000 network.

Please advise as to how to stop it showing as sometimes it even alarms as a dangerous target which is very irritating.

Thanks.
