Views of nodes create doubles when subdomain module is installed

I use subdomain for the following:

Authenticated users can create only one node type: seotags. These seotags are 'created' into subdomains by pathauto. So if somebody creates the node 'test' with node type 'seotags' pathauto makes it reachable through test.domain.com.

I created a view (block) that shows nodes of a certain type (seotag's) created by the logged in user. (His own seotags he can administer, edit, delete etc).

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, ...). If I uninstall the subdomain module, the doubles are gone as well.

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 ???
Or do I have to alter the settings for subdomain ? Right now in Domain Access settings, the main domain domain.com and www.domain.com are seen as one (all translate to domain.com). Maybe there lies the problem ?

I know the 'Distinct: Yes' in Views 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'; 
$view->tag = ''; 
$view->view_php = '';

$view->is_cacheable = FALSE; 
$view->api_version = 2; 
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
