We have set up a project in TFS 2012 and have begun creating tasks in our sprint backlog by opening the view in MS Project and then adding/syncing the new tasks using the MS Project 2010 integration. The tasks sync up fine into the work items views and I have verified that they are linked appropriately to some PBIs. That said, these tasks do not show up in the sprint backlog or board. I have verified that any task I create manually using the sprint backlog view directly in TFS does show up.
How can I make tasks show up in the backlog that I have created in Excel or MS Project and sync'd over into TFS?
