Which web browser are you using? It may have something to do with the browser, I was unable to reproduce the issue on either Firefox 10.0.1 or IE 9.
I was using Chrome, IE (7 and 9) and Firefox. They all had the same problem. However, the problem does not show on every page load.
Can you try reload a few times?
I was able to replicate the incorrect view one time. This might be a good one to send to our support team if you are still dealing with this issue. You can fill out a form at: http://www.tableausoftware.com/support/request
