Why is Aperture showing thousands of Rejected, but there are only 3 there? My Aperture is showing 2.5k Rejected photos (count), but when I view the album, there are only 3 there. I tried rebuilding the database.

I also tried switching and viewing the library in iPhoto, which shows no hidden photos. The library in Aperture shows no hidden photos. When I create a Smart Album having only Rejected items in it, it still only shows 3 items.

My Trash is empty too, and permissions are correct.

Any ideas on what's wrong, and why it's showing this?
Apparently aperture doesn't show photos that have been hidden in iPhoto. You need to open the library in iPhoto and unhide them there, I think. Then you can reject them in aperture again, and they should show up as expected.
