TF401094: This element defines a backlog for this team project. This PortfolioBacklog element and the following PortfolioBacklog element use the same work item type: '{0}'. The following work item type is used in both places: '{1}'. A work item type can not be used in multiple PortfolioBacklogs. If you have defined the same work item category for both PortfolioBacklog elements, you need to change the work item category for one of the PortfolioBacklog elements. If the work item type is defined in both work item categories, either you need to change the work item category for the PortfolioBacklog or you need to update the work item categories to contain distinct work item types.
