Doubles in view : Distinct Yes in View only works if 'Administer Nodes' rights are on... But...

I created a view (block) that shows nodes of a certain type (seotag's) created by the logged in user.

It shows doubles though; every node is shown twice, except if logged in as Administrator. Standard 'Recent posts' also show double if not loggin in (anonymous).

If I give authenticated users the rights to 'administer nodes' in user rights/permissions, the doubles are gone when they re logged in, BUT the authenticated users are also allowed to create other content types (pages, stories, ...).

Right now in permissions, they only have rights to

- create seotag content
- delete own seotag content
- edit own seotag content

How do I alter the view or the permissions so the view doesn't show each seotag twice ???

I know the 'Distinct: Yes' explains it doesn't always work, but how do I solve it ?

Here's an export of the view:

$view = new view; 
$view->name = 'own_content'; 
$view->description = 'own seo-tags';
