hello
i made a mistake when i cretaed some of my duct system
i created my ducts then i realised my mystake and i changed my duct system with the right name but... the system name didn't change
i created filters with the system name and, as some systems names are wrong my filters don't work

what is the best way to change to duct to the right system name?
I read that it's possible to change to unassigned item and to connect the duct to the right duct system but the duct system with its panel and its system tool is really, incredibly hard to understand

here a picture from the proporties of a duct
