Hi,
Normally, the filters are restricted by category in the settings of the filter. So the listing will only display the filters which match with the category selected in the filter and the current category.
So in your menu item, in the "main category" setting, you must have selected a category and you need to select that same category in the filters you want to display on that menu item.
Also, it's possible that the product/listing.php is customized in a wrong way preventing you from seeing the filters.
So check if you have the file templates/YOUR_TEMPLATE/html/com_hikashop/product/listing.php
If you do, rename the file and try again.
