Facet and content disappear after facet is selected

Hi everyone,

I've been struggling with this for a while now but I can't make the ajax facet work. Whenever I select a facet the whole block is hidden and all the content dissapear. It seems the view consider that the contextual validation filter failed.

I've tried on 2 very different indexes (one is generated with search_database and the other one with solr), used different views and different facets configured in different ways but it's always the same thing. I don't understand what I've been doing wrong.

Does anyone have an idea ?
