System.alarm.querystatus and empty display path

Hello,

I have noticed if I create a tag an assign an alarm then leave the display path blank this causes system.alarm.querystatus to return a false instead of a true. ]This seems like a bug, has anyone else noticed this? 8.1.37 is the version we are running.

source = ['*mypath*']
display = ['*']
result = system.alarm.queryStatus(source,display)

Regards,

Frank
