Is this a bug or am I doing something wrong here?

I use Zenphoto and the zenpage plugin (but I have it also without zenpage) with the zenpage default theme

I created some albums as categories with subalbums for the real pictures.
In each album I have placed a picture to serve as album-thumb.
In the properties of that picture I mark his as album thumb and clear the options Reaction possible and Visible.

On the site, when I open the album I see the subalbums but also the thumb-picture ???

OK, Can be closed :-(((.
I was still logged in as administrator. Sorry

No problem..:-)
