Problem Description

Since updating my workspace I am experiencing "Catalog item not found" errors with the following Plumbing Design tools:

From the "Pipe-Plumbing" toolbox:
Catalog item "BMP_DieElectricUnion:Default" not found 
Catalog item "BMP_Socket:Default" not found
Catalog item "BMP_MaleFemaleUnion:Default" not found
Catalog item "BMP_MaleFemaleUnion:Default" not found
Catalog item "BMP_Plug:Plug" not found
Catalog item "BMP_HexagonalBush:HexagonalBush" not found
Catalog item "BMP_HexagonalBush:HexagonalBush" not found

From the "Elbow-Plumbing" toolbox:
Catalog item "BMP_ElbowUnion:Default Elbow" not found
Catalog item "BMP_TwinElbow:TwinElbow"not found

From the "Plumbing Equipments" toolbox:
Catalog item "BMP_AirSeparator:Default" not found
Catalog item "BMP_AirSeparatorStrainer:Default" not found
Catalog item "BMP_AirSeparatorStrainer:Default" not found
Catalog item "BMP_AirSeparatorStrainer:Default" not found
Catalog item "BMP_StorageTank:StorageTank" not found

Which file(s) do these tools need to function? 

Steps to Resolve

All of these missing components are stored in the "PlumbingWaterSupply.xml" file, which by default is located in the workspace's \datagroupcatalogs folder; e.g., C:\ProgramData\Bentley\AECOsimBuildingDesigner V8i Ss5\WorkSpace\BuildingDatasets\Dataset_US\datagroupcatalogs

If you copy and paste this file from a known valid location it should resolve the errors.
