Can't view burndown charts after renaming team/project areas

I made changes to our server configuration Friday and today. A user pointed out this afternoon that they can no longer view burndown charts.

I created two new development "Lines" and their associated release and sprint plans. (Before we had one line, one release, and multiple sprints.)

Line 1
Release 1
Sprint 1
Sprint 2
...
Line 2
Release 2
Sprint 1
Sprint 2
..
Line 3
Release 3
Sprint 1
Sprint 2
..

I renamed our project and team areas to "WebSphere Commerce" from what they were, for example "Old Team Area Name" to "WebSphere Commerce" and "Old Project Area Name" to "WebSphere Commerce."

I can view a current burndown chart on the top-level, default team dashboard (Team Area: All, Iteration: Current Iteration) but I cannot view a burndown chart on any of the "Trends" or "Charts" tabs of the project areas. The message is "No work items with estimates specified were found."

I tried running the data warehouse task to see if it would refresh the data but that did change the results.

I noticed when trying to reconfigure the viewlets that the server seems to think the old team area name still exists, that is, I don't see the new name in the team hierarchy. I would expect to see /WebSphere Commerce/Team but instead I see /Old Team Area Name/Team.

Do I need to restart the server for project and team area renaming to take effect?
