Hello,
To display the terms and conditions box as always opened. Please insert the below css in Theme Settings >> CUSTOM CSS >> Global Custom CSS :
.woocommerce-terms-and-conditions{
display: block !important;
}
Find your Terms and Conditions page and make it in the default WordPress without WP Bakery page builder. Woocommerce does not support the WPBakery page builder in this type of pages.
WP Bakery elements not working in the terms and condition block you can check in this screenshot: https://jmp.sh/8JPHjJe
Best Regards.
