Problem assigning a view to a dashboard

Hi

As per the first attached screen image, I have created a view called
Opportunity Analysis v3_0 Filter based on the Opportunity Analysis report.

This view has a filter applied and is the version I need all users to see via a Dashboard however when I try to add this via HTML5 UI>Analysis>Dashboard>Selected Dashboard>Edit Dashboard it isn't available. Only the 4 reports in the second image are available.

What determines which views/reports are available as the source for dashboards?

 
Thanks
