Acrobat DC Pro does have the “Export Value”. Our version has it in the same location, and we are unable to find any version without the setting.
If you are still unable to locate the setting, you can upload the PDF form to PDFEscape.com to access the settings.
We would need to see the PDF form in order to specify the issue. Use this form to upload the PDF and/or provide access to your site for further review.
We remain at your service.
