Checkboxes displayed as checked after using back button even though they are not

Filters on my shop page

They are set to unchecked by default, when i go to shop page using navbar everything works well. However when i check some, go into single product page and press back there, view does not get updated even though checkboxes state is unchecked and all my products are displayed

for(let i=0; i<brandFilters.length; i++)
   console.log(brandFilters[i].checked) // logs 4x false

I tried forcing rerender by doing this, but it doesn't work.

for(let i=0; i<brandFilters.length; i++){
   brandFilters[i].style.display = 'none';
   brandFilters[i].style.display = 'block';
}

Any ideas how to solve this issue?
