Dashboard Duplication without connection to Original Dashboard

Am I completely mistaken, or was there an ability previously to duplicate a dashboard and the NEW "duplicate" dashboard be its own dashboard, not just a reference to the original dashboard with the same dashboard guid?  I know I had done this previously and it was a nice way to build off of another dashboard to enhance or expand the capabilities.

However, now it seems (or at least in my case) that when you duplicate a dashboard it just creates a reference to the original.  If I delete the duplicate, the original gets deleted.  If I rename the duplicate, the original gets renamed.  Is anyone else experiencing this?
