Paid/Free/All Filter does not work on search results beyond the first page of results.

You search for an item and you decide I really don't want to see paid models. So you click "free" and the paid results are removed from the first page. So far so good. However, when you click to go to page two or the next page if deeper in the results, the paid/free filter resets to "All" and paid models will be shown in the search results past the first page. The expected behavior is that the results would continue to only show the "free" or "paid" models depending on which choice you have selected once you are past the first page.
