Chosen working on one select but not other selects I'm facing a strange problem with the Chosen module. I've have 3 term-reference fields added to a content-type. 

While editing &amp; adding any nodes of this content-type, Chosen UI interface is applied &amp; working with all 3 fields. 

Now, I created a view and exposed the filters for all these three term-reference fields. In the view, Chosen UI interface is applied only to one field and not applied to the rest.

In the settings of chosen module (admin/config/user-interface/chosen)
Apply Chosen to the following elements is set to select

These are the Drupal settings outputed by Drupal into javascript:

"chosen":{
  "selector":"select",
  "minimum_single":"20",
  "minimum_multiple":"20",
  "minimum_width":"300",
  "search_contains":true,
  "disable_search":false,
  "disable_search_threshold":"Never Apply",
  "placeholder_text_multiple":"Choose some options",
  "placeholder_text_single":"Choose an option",
  "no_results_text":"No results match",
  "multiple":{
     "field_tags_tid[]":true,
     "field_working_area_tid":false,
     "field_published_in_tid[]":true
  },
  "max_selected_options":{
     "field_tags_tid[]":false,
     "field_working_area_tid":false,
     "field_published_in_tid[]":false
  }
   }
}


What might be the problem? How can I rectify it?

EDIT: Here is something interesting. When I manually enter jQuery('select').chosen() into the browser console, then other two exposed filters (select elements) which were not rendered as Chosen UI elements are now rendered. 

Any idea, about what might be wrong with it?
It looks like you have a 'Minimum number of options' setting of 20. I'm guessing the ones that don't display have less than 20 available options. Try setting this to 'always apply' on the Chosen settings form (admin/config/user-interface/chosen).
