In WCPA Pro version features like pricing, conditional logic and other JavaScript related features will not work in quick view popup that come along with flatsome theme.

It can fix only by directly modifying the JavaScript for quick view.  

It needs to run    jQuery.wcpaInit() after the quick view popup has loaded. 

Attached a modified file that need to be replaced at wp-content\themes\flatsome\assets\js\woocommerce.js 

Screenshot below show where we have added custom code
