i2b2 workbench doesn't expand previous patient sets properly

When expanding previous queries, a temporary node called is displayed with the text 'working .....'. Once the data is available, however, this node is not replaced. Refreshing does not correct this behavior. This occurs with queries which were run in previous sessions and the current session.

A workaround has been found, where if you open the views settings (the gears button) and apply a change, the patient sets will then be displayed until you close the application.
