Using breakdown with certain insight metrics throws error. Huge bug?

this query works: https://developers.facebook.com/tools/explorer/?method=GET&path=18025325167778997%3Ffiel[…]type)%7Bid%2Cname%2Cvalues%2Ctotal_value%7D&version=v19.0
This does not work: https://developers.facebook.com/tools/explorer/?method=GET&path=18025325167778997%3Ffields%3Did%2Cinsights.metric(impressions%2Creach%2Cshares%2Cnavigation).breakdown(story_navigation_action_type)%7Bid%2Cname%2Cvalues%2Ctotal_value%7D&version=v19.0
Why do I get an error (#100) Incompatible breakdowns (story_navigation_action_type) for metric (shares)?
Why can't I combine breakdowns like this: insights.metric(impressions,reach,shares,navigation,profile_activity).breakdowns(story_navigation_action_type,action_type)
