the theme previewer is displaying the default multi-site

Hi, the theme previewer is displaying the default multi-site theme screenshot on all template choices. It should display a screenshot to the respected template to be displayed on demo link. How can I fix this, I have tried the 2 answers in the forums that I found, but no luck. Is this a bug? If so, can Ignacio or one of the developers be flagged for a quick update on this.

Thank You
