I can't administrate my page though I'm the only administrator

Hi!

I'm the administrator of three facebook-pages:

[You must be registered and logged in to see this link.]

But the last one refuses to be administrated.
It does not appear on my startpage at "Pages".

I can see the administrator-view, but:
it does not show myself as administrator (and if I add myself as an administrator, nothing changes),
it does not show the image (which is shown on by facebooks URL-Linter)
and I can't see who liked the page ("No results found").

What ist wrong with that page?
