Box.com tree navigation fails

I have just two directory S9, S10
When I click into any directory it is not moving forward and shows in progress bar
When I refresh that screen it shows me duplicate directory with the same name. It adds duplicate everytime I refresh. Though I have just two directories in my box account i.e. s9, s10
