no calories on Garmin Swim2

Hi,

I thought a Garmin Swim2 is a supported device for calories in activityMonitor.info.

but the code

var HasCal = (AMon.getInfo() has :calories ) ? true : false;
Sys.println(HasCal);

gives true on a fr45 and false on a Garmin Swim 2

Is this correct  or a bug in the config?
