No photos on second page gallery

I use the plugin NextGen, version 2.0 and I created some galleries.

Only I have some gallery’s with 2 pages. The first pages are OK, but if you choose a second page there are no pictures shown. Please take a look what is happening…http://ligtjesweb.nl/fotoalbum/landschap-en-natuur/wordpress/nggallery/page/2
