When upgrading from Breakdance v1 to v2, the new layout feature for Sections or Divs won't be visible and you might still see the old layout. That's normal, if options have been set, the old layout will still be displayed.
If you want to access the new layout, you simply need to reset the settings.
Note that your previous settings will be erased, so you might need to configure the options again, but with the new layout this time.
