Hi, I faced a problem with the field collection creation in views.
For example, I created a content type and create a Field Collection - Address.
Within the Address I add few text field and a select list.
After that I created a list page using view and connected to the content type.
But the result in the list page is duplicated, if I input 3 address(field collection) in a content, 3 results with the same node-id will shows up.

FYI,
I added a field_collection relationship in the Views( to let me get access to the field in the field collection), and exposed the select list in the Field Collection for filter purpose.
I'm using Drupal 7 and Field Collection 7.x-1.0-beta5.
