Second Filtering reinitialised the result (No Ajax)

Hi, I’m not using ajax. The filter made from the home page works fine but, when I try to do another filter from another page, returns all products without any filtering. The result URL for the second filter show domain.ca/?sfid=1170 but not the rest of the filtering parameters. Unlike the first filtered that shows domain.ca/?sfid=1170&_sft_location=montreal&_sft_apartmenttype=2-bedroom and retrieve the correct product. I’m using the same shortcode in all the pages so I do not find the problem. I don’t know if I’m doing something incorrect or something is happen with the URL in the second filtering.
