Filtering the results on the results page with the plugin filters is unfortunately not yet possible. It is on the long list of features, and I’m hoping to have it implemented in the next two releases. Lots of testing awaits though.
However if you place the same search shortcode to the results page as the one that the redirection is coming from, then the filter statuses should be remembered. Unfortunately that still does not solve the problem with filtering the results page contents.Best,
