Facebook Insights API not returning all values

Using the Facebok API Explorer I just get a few values back from Facebook. I have an app that calls this API as well. Last week this was working properly, getting all values described here: https://developers.facebook.com/docs/reference/api/insights/

But now, here are the only values I'm getting back from Facebook:

• page_story_adds_unique (week)
• page_friends_of_fans (day)
• page_storytellers (week)
• page_admin_num_posts (week)
• page_admin_num_posts_by_type (day)
• page_admin_num_posts_by_type (week)

This is the request my app and the Facebook API is sending: https://graph.facebook.com/115893033044/insights?method=GET&format=json&access_token=XXXX

Does anyone know what might be the problem? Thanks!
