Hard to say why it's doing this but it looks like a faulty template.
Try restoring the list and details templates back to default and only in the main no-language default. Remove the other language list and details templates if you have them. You can tell if you've saved a template in a new language if it has a little flag on it.
There's information and saving and restoring individual templates at the bottom of this page:
