Relation with a specific view doesn't work

Hi,
When I create a new item with a relation field, if I let the relation at “no view”, it works (I see items that I can click on).
If I select a specific view (which has 19 items), it says No content found in related apps.
Though, I know there is 19 items in this view. Even when I enter some letters in the content box, related to an existing item in the related app, it doesn’t help.
I don’t understand what I am doing wrong…

Can you confirm that the view is public, and not private.
