object Style doesn't have Some Categories

[A_TX]

Hello,

After Installing Revit 2018 second update I figured out some categories like Data Devices, Fire Alarm Devices, and Communication Devices are not showing up in the object style. Does anybody know what happened to them? Did Autodesk removed them from categories permanently? 

Thank you!
