Ajax filter pagination problem

Hi,

The problem is on site https://blackleafgallery.com/shop.

1) I have an ajax filter plugin to filter products by attribute.
2) The shop is set to show 12 products per page.

When I filter by an attribute with more than 12 results (e.g. “Photograph”), I can only see 1 page of results. If I click Page 2 on the pagination, it just takes me to https://blackleafgallery.com/shop/page/2/ which contains unfiltered results.
