wrong share count

Hi, just another new thing I encountered with version 3.1.3:

The Backend gives me back a count of 25 for facebook, when it should be 205:

Facebook Debugger:
https://developers.facebook.com/tools/explorer/145634995501895/?method=GET&path=http%3A%2F%2Fschloss-post.com%2F&version=v2.5

{
  "og_object": {
    "id": "918419354915596",
    "description": "xxx",
    "title": "xxx",
    "type": "website",
    "updated_time": "2015-11-18T10:39:29+0000",
    "url": "http://xxx.com/"
  },
  "share": {
    "comment_count": 0,
    "share_count": 205
  },
  "id": "http://xxx.com/"
}

The results from your Backend for the same page:

{"facebook":25,"twitter":7,"googleplus":1,"xing":0,"linkedin":0,"pinterest":0,"errors":{"flattr":"Flattr Error! Message: ","vk":"VK Error! Message: "},"reddit":0,"stumbleupon":0,"tumblr":0,"addthis":1}

Also, it almost takes 20 seconds to load.

Any ideas?
