Hi,
That's a good catch.
There's actually a break; missing after the code:
case 'nouislider':
$doc->addScript(HIKASHOP_JS.'nouislider.min.js?v='.HIKASHOP_RESSOURCE_VERSION);
$doc->addStyleSheet(HIKASHOP_CSS.'nouislider.min.css?v='.HIKASHOP_RESSOURCE_VERSION);
$ret = true;
in the file administrator/components/com_hikashop/helpers/helper.php which lead to that file being loaded even when needed as long as you have a cursor filter on the page.
We'll add that patch on our end too to avoid loading it when not necessary. Thanks for the feedback.
