inawae that master item in expression I can rename the expression measure name . But when I try to rename the name in Visualisation name I cannot edit , what I need to do is create a new Visualisation items and enter the new name .
the point of master items is that they are the items you reuse so being the same is the point. If you need to rename it you probably need more than one master item or it may be it's not suitable to be a master item.
