AutoCAD Plant 3D Boolean property selection doesn't work

In AutoCAD Plant 3D's Project Setup, a True or False Boolean property can be added to existing equipment, such as a Horizontal Centrifugal Pump as shown below in the P&ID Class Definitions for Engineering Items, Equipment under Pumps. One common problem is that the Boolean choices for True or False are not available.


Shown is the SampleProject since the reported incident occurred with any project in AutoCAD Plant 3D 2019. This was also reproduced in Plant 3D 2020. A test Boolean property is added to the Horizontal Centrifugal Pump Style.


When the AutoCAD Plant Project Asset's properties are accessed, the True or False option cannot be changed.


But, it can be changed in the Data Manager.


The confirmed solution is an uninstall of AutoCAD Plant 3D, then a reinstall from the complete install source, using the Download Now method, with User Account Control set to Never Notify and the real-time antivirus scanner turned off. Then the Boolean choices for the custom property will now appear.
