So you have two solutions: - edit your categories listing menu items via the joomla menu manager, and change the item layout to something else, like the default "image and title" layout and save each one. - get the file templates/YOUR_TEMPLATE/html/com_hikashop/category/listing_blog.php from your old website and copy it to the same place for your Joomla 4 template on your new website at the same place.
