Cannot see work items assigned to sprint timeline within sprint plan using that timeline

You must ensure that the current sprint (an iteration) is set to 'current sprint'. In Manage this Project Area > Timelines > Defined Timelines, scroll down and highlight the sprint of interest.
On the Defined Timelines bar, on the right there is a small blue arrow by green/ yellow squares. If you hover over it, it will say 'Set Selected Iteration as Current' click this and the a small blue arrow should appear by your sprint of interest. This is now the current sprint and therefore all assigned work items can be seen in the sprint plan. Save your changes!
Make sure in the 'Edit Properties' of the Timelines, your current sprint- iteration has a tick against 'A release is scheduled for this iteration' in the edit box. Otherwise you will not be able to assign work items to the current sprint.
This is for release 4.0.6.
