Hello,
Sorry for the delay.
1. Please try to activate Storefront theme (Appearance > Themes > Install and activate) – official WC theme and check if you have this issue with our theme only or even with official theme too. If problem still persists then contact plugin support.
2. It requires additional customization in /royal/woocommerce/product-quick-view.php file. If you need help with additional customization you may contact WPKraken team because this is outside the scope of our support.
Regards,
Rose Tyler
