Some Portfolio Item titles contain the works "Portfolio Item" in the names while others do not.
Release : SAAS
Component : AGILE CENTRAL
The default Portfolio Item types do not contain "Portfolio Item" in the name, but if you have created custom Portfolio Item types they will include "Portfolio Item" to indicate what type of work item they are.
This is done to ensure that database queries from the UI and WSAPI, are using unique names and ensure that proper results are returned.
