Exposed Flags: Flagged filter doesn't work when node has translations

I use a view with an exposed Flags: Flagged filter. My need is to create a page with a search form on the flag. I can search for all the news, only the news flagged or only the news not flagged.

First of all I created the Relationship for my flag and I unchecked the "Include only flagged content" checkbox.
Then I created a filter on a Flags: Flagged; I choose the relationship; I put the status to All and I exposed the filter.

In my view I can search for the fields that are flagged or for the fields that are not flagged. It works without problem if the node is not translated.
But in my website I use two languages: English and French.

If I have a node which exists in English and in French and then I flag it, the flag is well put for the 2 languages but when I search for the nodes that are not flagged, this node is in the results but it should not be ...

Is there something wrong in the configuration of my view?

Thanks to help me
