Facebook URL Linter problem: different Admin URL values even though the og:app_id values are the same

We use the same og:app_id values for different pages, yet when we run those pages through the Facebook URL Linter开发者_JS百科, we see different values for the "Admin URL" property.

Any clues why?

Admin URL is unique for all pages and open-graph pages. Even though the administrator / owner application is the same. This Admin URL is where you can set settings for that specific page only. Try visiting that Admin URL and you will see it like a real page administration inside facebook.

You only use og:app_id for publishing stream into the open-graph page wall and other things that require administrative API action.
