In case the issue still persists, you're welcome to share a clone/snapshot of your website, with an updated Divi theme and the link to page(s) where the custom field values are missing.
( ref: https://toolset.com/faq/provide-supporters-copy-site/ )
This will allow troubleshooting, without affecting the live website and after sharing the clone, you'll be able to downgrade the theme on the live website again.
Please let me know how it goes and your next reply will be private.
regards,
Waqar
