Conflict with Pro Sites 3.5 and New Blog Template

I have a problem with the integration between Pro Sites 3.5 and New Blog Templates.

When selecting New Blog Templates to display the template options as "Theme Preview" the "View Demo" button does NOT open up the template for viewing. Prior to Updating Pro Sites to 3.5 the "View Demo" button in the template selection section opened up a new tab in the browser and displayed the destination of the Template site responsible for the template. Now it just refreshes to display the purchase package option. I would appreciate a speed resolution of this issue as we are on a very small time budget and need to implement this update ASAP.

I have tried disabling the other plugins however the problem persists.
