Portfolio page filter and pagination problem

Hi,

in the Portfolio page, the filter by category and the pagination doesn’t work well together: the filter works only on the images of the active page.

Please see here http://www2.residencecaporale.it/portfolio/ and filter by ‘Foto camere’: no photos will be showed because the 2 photos expected stay on page 2.

It’s possible to solve it?

Thanks,
Nikka
