I have tried that and its still not working:
https://www.pharmashaul.com/test-page/?p_asid=1&p_asp_data=1¤t_page_id=221&woo_currency=ILS&qtranslate_lang=0&filters_changed=1&filters_initial=0&aspf%5B_price__5%5D%5Blower%5D=0.00&aspf%5B_price__5%5D%5Bupper%5D=1000.00&asp_gen%5B%5D=title&customset%5B%5D=product&termset%5Bproduct_cat%5D%5B%5D=17&asp_s=&asp_id=1
This link when first loaded shows the correct 3 products that belong in the category, but if I then change the category in the filter on the right side. and remove T15/C3 and add T10//C2 only as in the attached image, i still get the 3 results from T15/C3 + the new one for T10/C2
(I have add a Category element to illustrate the problem on the page)
Its as if the parameters in the Querystring are always applied even if I undo them in the filter on the page.
I only want the parameters to set the initial display, but after that the Filter should take over
