Wrong vessel name sent

[robmicro]

Using the plugin with cerbo gx (venus os). I configured the vessel name in signalk. transmitting to my marinetraffic staion is ok. when I look at the marine traffic chart I can see your sailing boat and an other one called "venus". This follows our boat. When I switch stransmitting of, both boats disappear. where does the info from the second boat "venus" come from?
