i think its a bug in the filter module when i changed the category the filter not cleared automatically,
axample in your demo go to menu / shop / laptops filter by brand dell , i find one product
https://demo.sellacious.com/squick/index.php/product/dell-inspiron-core-i3-5th-gen-4-gb-1-tb-hdd-linux-z565155hin9-z565155uin9-3558-notebook-15-6-inch-black?s=513
now go to menu / shop / t-shirts oops no product in this category because the filter module not cleared automatically the t-shirts category filtred by brand dell
also if i filter by price and go to product detail the filter not cleared
thank you for your replay
