The quick view buttons are appearing twice!
If you are seeing unexpected things such as two quick view buttons for each product, then it may be that you have another type of quick view installed on your site as well as WooCommerce Quick View Pro. For example, perhaps you have another type of WooCommerce quick view plugin installed, or your theme provides its own quick view feature (such as Flatsome quick view).
Using two types of quick view together can cause conflicts and poor user experience.
WooCommerce Quick View Pro is designed to be the only quick view on your site, so you should disable any others. If you have another quick view plugin installed then you can disable it via the 'Plugins' list in the WordPress admin, or if your theme comes with built-in quick view then you can disable this in the theme options panel.
