How to get the privacy values with FQL query from stream table entries using a Facebook application?

I would like to know the privacy values (CUSTOM, ALL_FRIENDS, etc.) of the stream entries from a Facebook application, but the result does not contain privacy field values for all of the returned entries.

The application requests the following permissions: read_stream, export_stream, user_friends.

The query used by the application:

SELECT post_id, attachment, description, privacy 
FROM stream 
WHERE source_id = me() 
ORDER BY updated_time DESC 
LIMIT 20

The privacy part of the result looks like this for most of the entries (there are some which have privacy values):

...
"privacy": {
    "value": ""
}
...

If I filter for the value of the privacy field then it seems that only shared links have privacy values:

SELECT post_id, attachment, description, privacy 
FROM stream 
WHERE source_id = me() AND privacy.value != "" 
ORDER BY updated_time DESC 
LIMIT 20

I have already tried to run the query with all Facebook permissions available, the result was the same, no privacy values from the application.

But if I run the query in the Graph API Explorer with the same permissions, then I get the correct privacy values for all kinds of entries:

"privacy": {
    "description": "Public", 
    "value": "EVERYONE", 
    "friends": "", 
    "networks": "", 
    "allow": "", 
    "deny": ""
}

The fql query without any filters:

https://developers.facebook.com/tools/explorer?fql=SELECT%20post_id%2Cattachment%2C%20description%2C%20privacy%20FROM%20stream%20WHERE%20source_id%20%3D%20me()%20ORDER%20BY%20updated_time%20DESC%20%20LIMIT%2020

The fql query with privacy filter (privacy.value != ""):

https://developers.facebook.com/tools/explorer?fql=SELECT%20post_id%2Cupdated_time%2C%20attachment%2C%20type%2C%20description%2C%20privacy%20FROM%20stream%20WHERE%20source_id%20%3D%20me()%20AND%20privacy.value!%3D%22%22%20ORDER%20BY%20privacy.value%20DESC%20%20LIMIT%2020

These are the two apps' settings, although they look identical:

Any ideas how I can get the correct privacy values using a Facebook application?

If it works in the Graph API Explorer and doesn't in your app, something is wrong in your app. In my opinion, you most probably didn't successfully requested the permissions inside your app.

In your app settings, can you see the permissions you requested, just like on the picture?
