For example, an Attribute named "Status" in Catsy has always been an attribute that exists in Catsy by default. We have what we call "system" attributes and those are Category, Completeness Score, Item Type, Main Image, Name and Number. In Catsy, those Attributes are always highlighted in red and are different from the rest and will always be part of the hardcoded "system" attributes that exist within the system. You’ll notice that all of these system attributes are highlighted in Red.
