Product add on doesn’t respect conditional logics

Hi, i’m trying to create an estimate page by using your product builder plugin.
I’m getting this issue:
when i try to create a custom configuration it will open a popup where i can select the product and its addons.
I’m managing the product addons with this plugin:
https://wpdesk.net/products/flexible-checkout-fields-pro-woocommerce/

I set the product addons with some conditional logics that doesn’t correctly work inside your popup.
Please check your site information form to reply the issue.
Can you help me to fix it, please?
Thanks and regards.
Carlo
